(1) Two
(2) Three
(3) Four (4) One​

Answer 1

Answer:

(2) three

Explanation:

(c) option is not valid as cell wall is a dead layer so it is fully permeable to all substances (except pathogens which it hinders from entering by forming barriers) . Hence is unable to regulate the process. 'Cell membrane' has this function.

Hope it helps
