Action of cream and jelly is

The correct option is "spermicidal and immobilizing the sperms also".

Explanation:
Contraceptive creams, jellies, and foams are chemical barriers used for birth control. They contain spermicidal agents, most commonly nonoxynol-9, which work by disrupting the cell membrane of the sperms.
These contraceptive creams and jellies perform two primary functions when introduced into the vagina before intercourse:
1. They act as a spermicide, meaning they chemically kill the sperms.
2. They immobilize the sperms by reducing their motility, thereby preventing them from traveling up the female reproductive tract to fertilize the ovum.

Therefore, their action is spermicidal and immobilizing the sperms also.
