Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.841\% 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: O=C(CCc1c[nH]c2ccccc12)N1CCN(S(=O)(=O)c2ccccc2)CC1
b: CC(=O)Nc1cccc(NC(=S)Nc2ccc(F)cc2F)c1
c: COc1ccc(CCNC(=O)C2CCN(C(=O)c3cccs3)CC2)cc1
Answer: a. O=C(CCc1c[nH]c2ccccc12)N1CCN(S(=O)(=O)c2ccccc2)CC1
