Task: Answer the multiple-choice question.
Query: Which compound exhibits a 10.987% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(Cn1c(=O)cnc2ccccc21)N1CCN(S(=O)(=O)c2ccccc2Br)CC1
b: Cc1ccc2cc(/C=N/NC(=O)c3ccccc3[N+](=O)[O-])c(Cl)nc2c1
Answer: a. O=C(Cn1c(=O)cnc2ccccc21)N1CCN(S(=O)(=O)c2ccccc2Br)CC1
