Task: Answer the multiple-choice question.
Query: Which drug exhibits a 17.556\% 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(O)c1ccc(Cn2cnc3cccnc32)cc1
b: CN(CC(=O)Nc1ccc(Cl)c(C(F)(F)F)c1)C(=O)Cc1c[nH]c2ccccc12
c: C=CCN(c1ccccc1)S(=O)(=O)c1cccc(C(=O)O)c1
d: COc1ccc(CN=Nc2cc(C)nc(NS(=O)(=O)c3ccccc3Cl)n2)cc1
Answer: a. O=C(O)c1ccc(Cn2cnc3cccnc32)cc1
