Problem statement: Answer the multiple choice question.
Query: Which drug has a 11.134\% 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 additional words.
Options:
(a) COc1ccc(C2(CNC(=O)c3ccccc3[N+](=O)[O-])CCOCC2)cc1
(b) CCC1=CC2Cc3nc4ccc(Cl)cc4c(N)c3C(C1)C2
Answer: a. COc1ccc(C2(CNC(=O)c3ccccc3[N+](=O)[O-])CCOCC2)cc1
