Right answer is (a) True

The explanation: High capacity mobile systems are interference limited, but they are not noise limited. It was clearly seen that when carrier to interference ratio (C/I) is large, the errors are primarily due to fading, and interference has very little effect. However, as C/I drops below a certain level, interference dominates the link performance.
