Assertion : Plants utilizing first RuBP in `CO_(2)` fixations are clled `C_(3)` plants.
Reason : plants utilizing first PET in `CO_(2)` fixations are called `C_(4)` plants.

Options

A. If both the asserition and the reasion are true and the reason is a correct explanation of the assertion
B. If both the assertion and reasoni s not a correct ecplanation of the assertio
C. If the assertion is true but the reason is false
D. If both the asseertion and reason are false

Answer

B

Explanation

Plants that utilize primarily RuBP to fix `CO_(2)`, which results in the formation of the three-carbon compound 3-PGA, are called `C_(3)` plants. Hatch and Slack proposed a new pathway of `CO_(2)` fixation via the carboxylation of PEP. Because the products are four-carbon compounds, plants exhibiting this pathway are referred to as `C_(4)` plants.
