问题 Which of the following is the result, if a sunbather stays on the beach for a long time?
Why may the repair process of the DNA finally fail?

选项 A、Because shortwave radiant energy breaks the strands of the DNA.
B、Because the DNA may produce a colony of cancer cells.
C、Because enzymes work to rearrange the DNA into a new order.
D、Because the patient is exposed to UV from time to time.

答案B

解析题意：为什么DNA的修复过程最终可能会失败?因为DNA会导致癌细胞的生成。短文第三段提到“长时间的暴晒造成修复过程崩溃，并导致癌细胞的产生”，故选B。
