You are given a science question (hard-level) and four answer options (associated with "A", "B", "C", "D"). Your task is to find the correct answer based on scientific facts, knowledge, and reasoning. Do not generate anything else apart from one of the following characters: 'A', 'B, 'C', 'D'. There is only one correct answer for each question.

When an electric current is passed through water (H_{2}O) using a specific apparatus, hydrogen (H_{2}) and oxygen (O_{2}) gases form. How can this reaction be shown in a chemical equation?  
 (A) H_{2}O -> H + O + H (B) 2H_{2}O(l) -> 2H_{2}(g) + O_{2}(g) (C) H:O:H -> H_{2}O (D) H_{2}O(l) -> 2H(g) + O(g)
B
