Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 2.000\% 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] O=C(COc1ccccc1C(=O)N/N=C\c1ccc(O)c(O)c1)N/N=C/c1ccc(O)c(O)c1
[b] O=C(NCC(c1ccco1)N1CCN(c2ccccc2F)CC1)C(=O)NC1CCCCC1
Answer: a. O=C(COc1ccccc1C(=O)N/N=C\c1ccc(O)c(O)c1)N/N=C/c1ccc(O)c(O)c1
