Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Copper-T is surely one of the most effective methods of birth control. It releases Cu ions, which makes it difficult for the sperms to reach the uterus (and the egg). Hence it prevents fertilization. Copper- T can prevent pregnancies up to 10 years.
So the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
