Best answer
Correct choice is (c) Omni-directional

For explanation: Omni-directional suffers more co-channel interference compared to the sectored and smart antennas. Probability of collisions is reduced so the inference is also reduced in smart antennas. Thus, the Signal to interference (SIR) increases.
