If both the Assertion and Reason are incorrect.

(D) The Assertion is incorrect because optical waves (like those used in optical fibres) have a much higher frequency and bandwidth compared to microwaves,making them superior for signal transmission.The Reason is also incorrect because all electromagnetic waves,including microwaves and optical waves,travel at the same speed $(c = 3 \times 10^8 \ m/s)$ in a vacuum.Therefore,both the Assertion and the Reason are incorrect.
