Task: Answer the multiple choice question.
Query: Which compound exhibits a 25.933% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=C(O)CC1=C(Nc2ccccc2)C(=O)N(c2ccccc2)C1c1ccc(Br)cc1
(b) CN1CCC(NC(=O)Cc2c(F)cccc2Cl)CC1
Answer: a. O=C(O)CC1=C(Nc2ccccc2)C(=O)N(c2ccccc2)C1c1ccc(Br)cc1
