Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.018\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=c1[nH]c(SCc2ccc(Cl)cc2)nc2c1CCC2
b) COc1cccc(OCCn2cc(C(C)=O)c3ccccc32)c1
c) O=S(=O)(Cc1ccccc1)N1CCN(Cc2ccccc2)CC1
Answer: a. O=c1[nH]c(SCc2ccc(Cl)cc2)nc2c1CCC2
