Best answer
The correct choice is (a) Diversity

To explain: Diversity transmission and reception can reduce the probability of non-recoverable fade depth. It tends to choose the signal with maximum strength, improving the error floor. FEC and interleaving are useful for compensating the erasure caused by fading.
