Task: Answer the multiple-choice question.
Query: Which drug has a 7.266\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: C=CCSc1nnc(NC(=O)C2CSC3(C)CCC(=O)N23)s1
b: O=C(N=Nc1c(O)[nH]c2ccc([N+](=O)[O-])cc12)c1cc(-c2ccccc2Cl)nc2ccccc12
c: Cc1cc2c(c(SCC(=O)NCc3ccccc3Cl)n1)C(=O)OC2
Answer: b. O=C(N=Nc1c(O)[nH]c2ccc([N+](=O)[O-])cc12)c1cc(-c2ccccc2Cl)nc2ccccc12
