A. Artificial intelligence is complete changing the medical industry.

B. Artificial intelligence is revolutionizing the medical industry.

C. Artificial intelligence totally changes the medical industry.

D. Artificial intelligence has revolutionized the medical industry.

核心考点：中英动词短语的准确对应。解题思路：'彻底改变'对应revolutionize（根本性变革）。选项B使用现在进行时准确描述持续变革。选项A语法错误（complete为形容词）。选项C/D时态不符合原文'正在'。易错点：忽视时态和动词形式的选择。
