Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.940\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CN1CCC(N(C)S(=O)(=O)c2ccc(F)cc2F)CC1
b: S=c1[nH]nc(COc2cccc(Cl)c2)n1Cc1ccccc1
c: CN1CCN(C(=O)c2cc(Br)cn2C)CC1
d: Cc1nc(CSc2ccc(Cl)cc2)cs1
Answer: a. CN1CCC(N(C)S(=O)(=O)c2ccc(F)cc2F)CC1
