Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 16.300\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1nc(SCC(=O)OCc2ccccc2)c2c(=O)n(C)c(=O)n(C)c2n1
b: O=c1cc(-c2ccc(Br)cc2)[nH][nH]1
c: Cc1ccc(CCN2C(=O)CCC2(C)C(=O)NC2CCCC2)cc1
d: COC(=O)c1cc(NC(=O)CSc2nncn2C)cc(C(=O)OC)c1
e: COc1ccccc1C(=O)COC(=O)CN1C(=O)C2CC=CCC2C1=O
Answer: b. O=c1cc(-c2ccc(Br)cc2)[nH][nH]1
