Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 17.812% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCOc1ccc(-c2nc(CSCC(=O)NCC3CCCO3)c(C)o2)cc1
b: O=C(c1cccc([N+](=O)[O-])c1)N1CC2C3C=CC(C3)C2C1
Answer: b. O=C(c1cccc([N+](=O)[O-])c1)N1CC2C3C=CC(C3)C2C1
