Task: Answer the multiple choice question.
Query: Which drug exhibits a 14.462\% 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) CC1(c2cccc(Br)c2)NC(=O)N(CC(=O)Nc2cccnc2Cl)C1=O
(b) CCOc1ccc(CCNC(=O)CN2C(=O)c3cccnc3Oc3ccc(Cl)cc32)cc1
Answer: a. CC1(c2cccc(Br)c2)NC(=O)N(CC(=O)Nc2cccnc2Cl)C1=O
