Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.313\% human ether-à-go-go related gene (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=C(NCc1ccco1)c1cccnc1Cl
b: CC(C)[C@H](NC(=O)[C@@H]1Cc2ccccc2CN1)C(=O)NC1CCCCC1
c: CCCSCCCNC(=O)CN1C(=O)COc2ccc(S(=O)(=O)N3CCCC3)cc21
d: Cc1cc(C(=O)NC(C)C)on1
e: Cc1nc(NC(=O)CSc2cc(C)c3ccccc3n2)c(Cl)cc1Cl
Answer: a. O=C(NCc1ccco1)c1cccnc1Cl
