Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.554\% human ether-à-go-go related gene (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 COc1ccc(S(=O)(=O)NCc2ccccn2)c(C)c1C
b COc1ccc(OC)c(NC(=O)c2ccc(CSc3ncccn3)cc2)c1
c O=C(C1CCC(CNc2c(N3CCCCC3)c(=O)c2=O)CC1)N1CCN(C2CCCCC2)CC1
d CCOC(=O)CNS(=O)(=O)c1ccc(S(=O)(=O)NC2CC2)cc1
Answer: a. COc1ccc(S(=O)(=O)NCc2ccccn2)c(C)c1C
