Task: Answer the multiple-choice question.
Question: Which compound has a 12.299% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
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]cnc2cc(-c3ccc(Br)cc3)sc12
b.) CSc1nc2ccc3nc(NC(=O)c4ccc(C)cc4)sc3c2s1
c.) CCOc1ccc(NS(=O)(=O)c2ccc(NS(=O)(=O)c3ccccc3)cc2)cc1
d.) O=c1c2c(nc3nc(NCc4ccccc4Cl)[nH]n13)CCC2
Answer: a. O=c1[nH]cnc2cc(-c3ccc(Br)cc3)sc12
