The correct option is C Saheli
Progestasert, etonogestrel implant and transdermal patch are steroid hormone containing contraceptives. They have progestogen or a combination of both progestogen and estrogen.
These contraceptives might have side effects.
Saheli is a non-steroidal pill which contains a chemical that prevents implantation of the fertilised egg. As it is a non-steroidal pill, the side effects are very less. Saheli does not disturb the hormonal balance of the female.
