Until recently, there were no experimental reports of superconductivity in graphene although its close relatives, graphite and fullerenes can be made superconducting by intentionally introducing electrons in the material (doping).
For the British literary movement, see Spasmodic poets. A spasm is a sudden involuntary contraction of a muscle, a group of muscles, or a hollow organ such as the heart. A spasmodic muscle contraction may be caused by many medical conditions, including dystonia. Most commonly, it is a muscle cramp which is accompanied by a sudden burst of pain.
Voluntary movement means the movement is control by the person. Such as in walking, or stooping. You make the muscle move. Involuntary means the muscle the muscle moves without any control from you, like your heart beating. Based on this A & B are wrong. They are actually the reverse of the statement.
