Two plants A and B are supplied with `CO_(2)` with `H_(2)O^(18)` and releases `O^(18)` type oxygen in photosynthesis

Options

A. A plant
B. B plant
C. Both (a) and (b)
D. First (a) and then (b)

Answer

A

Explanation

During photosynthesis `O_2` evolved by the hydrolysis of water. If `H_(2)O^(18)` is used in 'A' plant then it become true that `O^(18)` type oxygen evolved from 'A' plant during photosynthesis.
