Assertion:Water absorption is reduced by lowering `O_2` tension.
Reason : The accumulation of `CO_2` reduces water absorption.

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If both the assertion and reason are false

Answer

B

Explanation

In water absorption the accumulation of `CO_(2)` creating tension for water absorption. An increase in `CO_(2)` causes an increase in viscosity of protoplasm and the decrease in root permeability to water
