Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.391\% 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) CCOc1ccccc1NC(=O)NC1(C(=O)N2CCOCC2)CCCCC1
(b) CCOC(=O)N1CCC(N2CCN(S(=O)(=O)c3ccc4ccccc4c3)CC2)CC1.O=C(O)C(=O)O
Answer: b. CCOC(=O)N1CCC(N2CCN(S(=O)(=O)c3ccc4ccccc4c3)CC2)CC1.O=C(O)C(=O)O
