Assertion : Communication in UHF/VHF regions can be established by space wave or tropospheric wave. Reason : Communication in UHF/VHF regions is limited to line of sight distance.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion

Step-by-step solution

As UHF/VHF waves are not reflected by ionosphere being of higher frequency.
