Task: Answer the multiple-choice question.
Question: Which compound exhibits a -2.195% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) C/C(=C/C(=O)O)C(=O)Nc1cccc(C(F)(F)F)c1
b.) CCc1nn(-c2ccccc2)c(N)c1C#N
c.) COCCN(C(=O)COC(=O)COc1ccc(Cl)c(C)c1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
d.) Cc1ccc(CN(C)C(=O)c2ccc(NS(=O)(=O)c3ccc4[nH]c(=O)[nH]c4c3)cc2)cc1
Answer: b. CCc1nn(-c2ccccc2)c(N)c1C#N
