Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.640\% 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=C(Nc1ccccc1)/C(=C\c1ccc2c(c1)OCO2)NC(=O)c1ccco1
b: CC(=O)Nc1ccc(S(=O)(=O)Nc2nc(-c3ccc(C(C)(C)C)cc3)cs2)cc1
c: Cn1cc(S(=O)(=O)CC(=O)Nc2ccc3c(c2)OCO3)c2ccccc21
d: CCCC(=O)N1c2ccc(-c3csc(N)n3)cc2CC1C
Answer: d. CCCC(=O)N1c2ccc(-c3csc(N)n3)cc2CC1C
