Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 20.816\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C(NNc1c2ccccc2nc2ccccc12)C(O)c1ccccc1
(b) O=C(CCNC(=O)c1ccc(Br)cc1)Nc1ncccc1O
(c) O=C(O)c1cccc(Nc2nc(N3CCOCC3)nc(N3CCOCC3)n2)c1
Answer: b. O=C(CCNC(=O)c1ccc(Br)cc1)Nc1ncccc1O
