Problem statement: Answer the multiple choice question.
Query: Which drug has a -4.022\% 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, d, or e without using any additional words.
Options:
a CCN(CC)c1ccc(CNc2nnnn2C)cc1
b O=C(N/N=C/c1ccc[nH]1)c1sc2ccccc2c1Cl
c CN(CCc1ccccn1)C(=S)Nc1ccc(Cl)c(Cl)c1
d COc1ccc(C(=O)N2CCN(c3ccc([N+](=O)[O-])c(NCCc4ccc(OC)c(OC)c4)c3)CC2)cc1
e Cc1c(NC(=O)C(C)n2cc([N+](=O)[O-])cn2)c(=O)n(-c2ccccc2)n1C
Answer: b. O=C(N/N=C/c1ccc[nH]1)c1sc2ccccc2c1Cl
