The following events occur during the process of photosynthesis. Choose the option that indicates the correct events. 1

(i) Oxidation of carbon dioxide to carbohydrates

(ii) Conversion of light energy into chemical energy

(iii) Absorption of light energy by chlorophyll (iv) Conversion of hydrogen and oxygen into water

Options :

(A) (i) and (ii)

(B) (ii) and (iii)

(C) (iii) and

(iv) (D) (i) and (iv)

Correct answer: (B) (ii) and (iii)

Explanation:

During photosynthesis, the correct events are:

(ii) Conversion of light energy into chemical energy

(iii) Absorption of light energy by chlorophyll

Chlorophyll absorbs sunlight, and this light energy is converted into chemical energy during photosynthesis.

The other statements are incorrect because:

(i) Carbon dioxide is reduced to carbohydrates, not oxidised.

(iv) Water is split into hydrogen and oxygen; hydrogen and oxygen are not converted into water.
