Solution

The correct option is C Assertion is correct but Reason is incorrect
As the distance increases $T V$ signals becomes weaker. So , assertion is correct . The power transmitted from $T V$ transmitter is inversely proportional to the square of the distance of the receiver.That's why reason is incorrect .
