Answer:
Correct Answer: C
Solution:
The television signals being of high frequency are not reflected by the ionosphere.
So the T.V. signals are broadcasted by tall antenna to get large coverage, but for transmission over large distance satellites are needed.
That is way, satellites are used for long distance T.V. transmission.
