Task: Answer the multiple-choice question.
Query: Which drug exhibits a 0.672% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCN(CC)CCNC(=O)c1cn(C)c2ccc(S(=O)(=O)N(C)C3CCCCC3)cc2c1=O
(b) CCOC(=O)c1ccc(-c2ccc(/C=N/NC(=O)c3cncc(Br)c3)o2)cc1
Answer: b. CCOC(=O)c1ccc(-c2ccc(/C=N/NC(=O)c3cncc(Br)c3)o2)cc1
