Why is transcription-coupled repair (TCR) considered particularly efficient when compared to nucleotide excision repair (NER)?

A. The exinuclease employed in TCR removes a smaller fragment containing the damage.
B. TCR targets transcriptionally active regions for repair over damage in less active parts of the genome.
C. It uses error-prone polymerases so it can move through damaged areas faster.
D. It directly repairs the damage rather than removing and replacing the damaged strand.
E. TCR requires less protein interactions.
