Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 13.039\% 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.) COc1ccc(-c2cc(-c3ccccc3O)[nH]n2)cc1
b.) O=C(O)c1cc2c(ccc3ccccc32)[nH]1
c.) Cc1occc1-c1nnc(SCC(=O)N(C)CCC#N)n1N
d.) Cc1ccc(OCC(=O)NNC(=S)NC(=O)C(C)(C)C)c(Br)c1
Answer: b. O=C(O)c1cc2c(ccc3ccccc32)[nH]1
