Answer - C - In an environment where frame retransmission is common, the data throughput may decrease.

Key Takeaway: In a noisy environment, the fragmented frames contain more bits than un-fragmented frames. If frames need to be retransmitted, it is possible that the overall number of bits transmitted is actually less than if the frames had not been fragmented. In such a case, the throughput may increase or decrease, depending upon how many frames are retransmitted.
