Task: Answer the multiple-choice question.
Query: Which drug exhibits a 15.455\% 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 additional words.
Options:
a Cc1nn(-c2ccccc2)c(C)c1/C=N/NC(=O)c1cnccn1
b Cc1ccc(S(=O)(=O)N(CC(=O)NCC2CCCO2)C2CCCCC2)cc1
c Cc1ccc(C=Nc2cc([N+](=O)[O-])ccc2C)s1
d Cc1ccc(S(=O)(=O)CCC(=O)NCCc2ccc(Cl)cc2)cc1
Answer: c. Cc1ccc(C=Nc2cc([N+](=O)[O-])ccc2C)s1
