Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.942\% 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) Nc1ccc(C(=O)NC2CCSc3ccccc32)cc1[N+](=O)[O-]
b) COc1ccc2c3c([nH]c2c1)C(C)=NCC3
c) CC(=O)CSc1ncnc2nc[nH]c12
Answer: b. COc1ccc2c3c([nH]c2c1)C(C)=NCC3
