Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 0.256\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: Cn1nc(NC(=O)CC23CC4CC(CC(C4)C2)C3)c2c(F)cccc21
b: COc1cc(OC)c(CN2CCCCCCC2)cc1Br
c: CCN(CC)CCNC(=O)c1ccc(Cl)c(S(=O)(=O)Nc2ccc(Cl)cc2)c1
d: NNC(=O)c1ccc(Cn2cccn2)o1
e: CCOC(=O)CNC(=O)CNC(=O)Cn1ccc2ccccc2c1=O
Answer: b. COc1cc(OC)c(CN2CCCCCCC2)cc1Br
