Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.403\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C(OCc1nnc(-c2ccccc2)o1)c1ccccc1
b: Cc1cc2ncn(CCC(=O)NC(C)(C)C)c2cc1C
c: CCC(C)n1ncn(-c2ccc(N3CCN(c4ccc(OC)cc4)CC3)cc2)c1=O
d: CCOC(=O)c1nnc2cc(-c3ccc(Br)cc3)nn2c1C
e: CC(=O)Nc1cccc(-n2nnc(SCC(N)=O)n2)c1
Answer: c. CCC(C)n1ncn(-c2ccc(N3CCN(c4ccc(OC)cc4)CC3)cc2)c1=O
