You will be given a definition of a task first, then some input of the task.
In this task, you are given a context, a subject, a relation, and many options. Based on the context, from the options select the object entity that has the given relation with the subject. Answer with text (not indexes).

Context: Sinistral and dextral , in some scientific fields , are the two types of chirality ( `` handedness '' ) or relative direction . The terms are derived from the Latin words for `` left '' ( sinister ) and `` right '' ( dexter ) . Other disciplines have different terms ( such as dextro - and laevo - rotary , in chemistry , or clockwise and anticlockwise in physics ) or simply use left and right ( as in anatomy ) . Relative direction and chirality are distinct concepts . Relative direction is from the point of view of the observer . A completely symmetrical object has a left and a right side , from the observer 's point of view , if the top and bottom and direction of observation are defined . Chirality , however , is observer - independent : no matter how one looks at a right - hand screw thread , it remains different from a left - hand screw thread . Therefore , a symmetrical object has sinistral and dextral directions arbitrarily defined by the position of the observer , while an object that has chirality can have sinistral and dextral directions defined by characteristics of the object , no matter the position of the observer ., Handedness is a better (faster or more precise) performance or individual preference for use of a hand, known as the dominant hand. Handedness is not a discrete variable (right or left), but a continuous one that can be expressed at levels between strong left and strong right., In classical physics and special relativity, an inertial frame of reference (also inertial reference frame or inertial frame, Galilean reference frame or inertial space) is a frame of reference that describes time and space homogeneously, isotropically, and in a time-independent manner. The physics of a system in an inertial frame have no causes external to the system., Physics (from , from "phúsis" "nature") is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves., The most common relative directions are left, right, forward(s), backward(s), up, and down. No absolute direction corresponds to any of the relative directions. This is a consequence of the translational invariance of the laws of physics: nature, loosely speaking, behaves the same no matter what direction one moves. As demonstrated by the Michelson-Morley null result, there is no absolute inertial frame of reference. There are definite relationships between the relative directions, however. Left and right, forward and backward, and up and down are three pairs of complementary directions, each pair orthogonal to both of the others. Relative directions are also known as egocentric coordinates., Subject: sinistral and dextral, Relation: instance_of, Options: (A) behavior (B) direction (C) energy (D) force (E) frame of reference (F) motion (G) null (H) performance (I) physics (J) result (K) space (L) three (M) variable
