Answer: B. Water breaks down into oxygen molecules for respiration.

Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.

$6CO_2\ \ \ \ +6H_2O\rightarrow\ C_6H_{12}O_6+6O_2\\carbon\ \ \ \ water\ \ \ \ \ \ \ \ glucose\ \ \ \ \ \ \ oxygen\\ dioxide$

This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.
