Final answer:
In the context of antenna alignment, a vertical alignment of a receiving antenna relative to the transmission from a vertical transmitting antenna typically provides better reception. If discussing a loop antenna's alignment, it should be perpendicular to the direction of the radio waves for optimal signal reception.
Step-by-step explanation:
The original question appears to be mixing elements of television positioning and the alignment of antennas to optimize reception. However, the student may be asking about the optimal alignment of a receiving antenna relative to the transmitting antenna. For an antenna to best receive radio waves broadcast by a vertical transmitter antenna, the receiving antenna should also be oriented vertically. This is why option b) Vertical alignment is preferred for better viewing could be considered correct in the context of antenna alignment, although the wording 'for better viewing' seems a little off-context and may apply more to how a television is positioned in a room rather than the actual antenna alignment for signal reception. If the question is pertaining to how a loop antenna should be aligned to receive signals best, it should be placed perpendicular to the direction of the radio waves. The loop antenna's plane should be aligned such that it's facing the direction of the signal for optimal reception.
