Problem statement: Answer the multiple-choice question.
Query: Which drug has a 16.486\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) CCn1cc(C(=O)NCc2ccccc2Cl)cn1
b.) Cc1c(N=Nc2c(O)[nH]c(=O)[nH]c2=O)c(=O)n(-c2ccccc2)n1C
c.) CNC(=O)c1csc(Cc2c(Cl)sc3ccc(Cl)cc23)n1
d.) CC(C)c1ccc(S(=O)(=O)N2CCN(C(=O)c3ccc(N4CCCC4)c([N+](=O)[O-])c3)CC2)cc1
Answer: b. Cc1c(N=Nc2c(O)[nH]c(=O)[nH]c2=O)c(=O)n(-c2ccccc2)n1C
