Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.616\% 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] O=C(CCOc1ccccc1)Nc1ccccc1F
[b] Cc1ccc2nc(SCC(=O)N/N=C/c3ccc(C(=O)O)cc3)cc(C)c2c1
Answer: a. O=C(CCOc1ccccc1)Nc1ccccc1F
