Task: Answer the multiple-choice question.
Question: Which compound exhibits a -3.809\% 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 additional words.
Options:
a CN(CC(=O)O)S(=O)(=O)c1cc(Cl)ccc1Cl
b COc1ccc(CC(=O)NC(C)(C)CC(C)=O)cc1OC
c Cc1sc(NC(=O)CN(CCc2ccccc2)C(=O)C2CC2)c(C(N)=O)c1C
d CCCc1nc2ccccc2[nH]1
Answer: b. COc1ccc(CC(=O)NC(C)(C)CC(C)=O)cc1OC
