• A. Water splits.
• B. CO${}_2$ is assimilated to organic compound.
• C. Chlorophyll is activated.
• D. 6 carbon sugar is broken down into 3 carbon sugar.

Answer 1

The correct option is B CO${}_2$ is assimilated to organic compound.

During dark reaction of photosynthesis, CO${}_2$ is assimilated to organic compounds, like glucose. This phase occurs in absence of light, so called as dark reaction. CO${}_2$ is assimilated in presence of the enzyme RuBisCo.
