Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 8.278\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COc1ccc(C(=O)NC(CC(C)C)C(=O)O)cc1OC
b: COC(=O)N/N=C/c1cc(OC)c(O)c([N+](=O)[O-])c1
Answer: b. COC(=O)N/N=C/c1cc(OC)c(O)c([N+](=O)[O-])c1
