Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.010\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. O=C1NN=C(c2ccc(Cl)cc2)CC1c1cccc(Br)c1
b. O=C(CSc1nnc(NC(=O)c2c(F)cccc2F)s1)NCc1ccccc1
c. CC1CCCCC1NC(=O)c1ccc(N2CCCC2=O)cc1
d. COc1ccc(-c2csc(Nc3ncccc3C)n2)cc1OC
e. COC(=O)c1ccc(CN2[C@H](C(=O)OC)C[C@@]3(O)[C@@H](O)[C@@H](O)[C@@H](O)C[C@@H]23)cc1
Answer: a. O=C1NN=C(c2ccc(Cl)cc2)CC1c1cccc(Br)c1
