Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 16.787\% 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(C2CC(=O)N(CCC[NH+](C)CCc3ccc(OC)c(OC)c3)C2)cc1.O=C([O-])C(=O)[O-]
(b) COc1cc2c(cc1OC)C(c1ccccc1[N+](=O)[O-])N(C(C)=O)CC2
Answer: b. COc1cc2c(cc1OC)C(c1ccccc1[N+](=O)[O-])N(C(C)=O)CC2
