Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.864\% 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. NC(=O)CC(NC(=O)Cc1ccc(Cl)cc1)c1ccc(NC2CC3CCC2C3)c([N+](=O)[O-])c1
b. O=C(CCSc1nnc(-c2ccncc2)o1)Nc1ccccc1
c. Cc1ccc(NC(=O)COC(=O)CCc2ccccc2)c(Cl)c1
d. COC(=O)C1(C)NC(c2ccccc2F)C2C(=O)N(c3ccccc3)C(=O)C21
e. CC1CCN(C(=O)CNC(=O)CNS(=O)(=O)c2ccccc2)CC1
Answer: b. O=C(CCSc1nnc(-c2ccncc2)o1)Nc1ccccc1
