Task: Answer the multiple choice question.
Query: Which drug exhibits a 17.565% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(CSc1cccc2cccnc12)NCc1ccco1
b: O=C(O)c1ccc(S(=O)(=O)c2ccc3c(c2)C(=O)N(c2ccccc2[N+](=O)[O-])C3=O)cc1
c: O=C(c1ccc(Cl)c(Cl)c1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
d: CC(C)C(=O)c1cn(CC(=O)NCc2ccc3c(c2)OCO3)c2ccccc12
Answer: b. O=C(O)c1ccc(S(=O)(=O)c2ccc3c(c2)C(=O)N(c2ccccc2[N+](=O)[O-])C3=O)cc1
