Explanation
Answer - A - Omni-directional antennas are used when all horizontal directions from the antenna should form a coverage zone.

Key Takeaway: An Omni-directional antenna is an antenna system that radiates power uniformly in one plane with a directive pattern shape in a perpendicular plane. This provides complete coverage in the shape of a doughnut horizontally around the antenna. Omni-directional antennas are constructed using co-linear dipole arrays.
