Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 2.866\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(NCc1cccnc1)c1ccc(-c2cccc([N+](=O)[O-])c2)o1
b: CC1CN(Cc2c(O)ccc3c(=O)c(-c4ccccc4)coc23)CC(C)O1.Cl
c: CCOc1ccc(CCNC(=O)Cn2ccc3ccccc3c2=O)cc1OCC
d: Clc1cccc(-c2nnc(-c3ccccc3)o2)c1
e: CC1=C(C(N)=O)C(c2cccnc2)n2nc(SCc3ccccc3Cl)nc2N1
Answer: b. CC1CN(Cc2c(O)ccc3c(=O)c(-c4ccccc4)coc23)CC(C)O1.Cl
