Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.236\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) CCN(CC)S(=O)(=O)c1ccc2[nH]cc(C(=O)NC3CC3)c(=O)c2c1
b.) COCCN1C(=O)/C(=C/c2ccc(Oc3ccc([N+](=O)[O-])cn3)c(OC)c2)SC1=Nc1ccccc1
c.) O=C(CSc1n[nH]c(-c2ccccc2)n1)Nc1ccc(F)cc1F
Answer: a. CCN(CC)S(=O)(=O)c1ccc2[nH]cc(C(=O)NC3CC3)c(=O)c2c1
