Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Plants lack excretory organs hence excretory material are stored in vacuoles and cytoplasm of the cells of different plant organs. So, assertion is correct. Plants absorb essential nutrients from soil and do not show locomotion. Therefore, reason is correct. However plants release out certain excretory materials like gases through pores and liquids as exudates.
So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'
