Task: Answer the multiple choice question.
Query: Which compound exhibits a 14.876\% 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, c, or d without using any other words.
Options:
a O=c1[nH]c(SCc2cccc(Cl)c2)nc2[nH]ncc12
b O=C(CN1CCN(C(=O)C2CCCO2)CC1)Nc1ccc(Br)cc1
c COc1ccccc1NC(=S)N1CCN(c2ccccc2F)CC1
d CC(=O)Nc1ccc(C(=O)NNC(=O)Cc2ccccc2)cc1
Answer: c. COc1ccccc1NC(=S)N1CCN(c2ccccc2F)CC1
