Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 0.730\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C1c2ccncc2C(=O)N1CO
(b) Cc1ccc(-c2nnc(CSc3nc4cc5c(cc4cc3C)OCO5)o2)cc1
(c) O=C(COc1ccc2ccccc2c1)Nc1cccc2c1C(=O)NC2=O
(d) COc1ccccc1OP(C)(=O)Nc1ccccc1Br
Answer: d. COc1ccccc1OP(C)(=O)Nc1ccccc1Br
