Task: Answer the MCQ question.
Question: Which drug exhibits a 10.870% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: NS(=O)(=O)c1ccc(CCNC(=O)CCCC2=NS(=O)(=O)c3ccccc3N2)cc1
b: CC1=C(c2ccc(Cl)cc2)[N+](=O)C(C)(C)N1[O-]
c: CCSc1nnc(NC(=O)CSc2nnc(CNC(=O)c3cc(OC)c(OC)c(OC)c3)o2)s1
Answer: b. CC1=C(c2ccc(Cl)cc2)[N+](=O)C(C)(C)N1[O-]
