Task: Answer the multiple choice question.
Query: Which compound has a 16.648\% 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 additional words.
Options:
[a] CCOc1ccc2[nH]c(C(=O)N/N=C/c3cc(OC)c(OC)c(OC)c3)cc2c1
[b] O=C(N/N=C/c1ccc(Cl)cc1Cl)c1cccc(F)c1
Answer: a. CCOc1ccc2[nH]c(C(=O)N/N=C/c3cc(OC)c(OC)c(OC)c3)cc2c1
