Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.432\% 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 S=c1[nH]nc(-c2ccco2)n1/N=C/c1ccc(Cl)cc1Cl
b COc1cc(N2Cc3ccccc3C2)ccc1C=O
c COc1ccc(-c2csc(NC(=S)NC(=O)c3ccccc3)n2)cc1Br
Answer: b. COc1cc(N2Cc3ccccc3C2)ccc1C=O
