Text Solution

Verified by Experts

The correct Answer is:
A
Both assertion and reason are true and reason is the correct explanation of assertion.
Optical fibers are used in communication and it is because the phenomenon and it is because the phenomenon of total internal reflection, taking place inside the fiber for the signal incident. Both the statements are correct and the reason given is the right explanation.
