Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.521\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a COc1nn(CC(=O)N2N=C(C)CC2(O)C(F)F)cc1[N+](=O)[O-]
b O=C(c1cc(F)ccc1F)C1CCCN(C(=O)c2ccc3nccnc3c2)C1
Answer: a. COc1nn(CC(=O)N2N=C(C)CC2(O)C(F)F)cc1[N+](=O)[O-]
