Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.397\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) Nc1ccc(S(=O)(=O)c2cccc(N)c2)cc1
b.) O=C(CN1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1)NC(=O)NC1CCCCC1
c.) CCCCCC(=O)Nc1nc(C)c(-c2csc(Nc3ccccc3OC)n2)s1
Answer: b. O=C(CN1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1)NC(=O)NC1CCCCC1
