Problem statement: Answer the multiple choice question.
Question: Which compound has a -2.741% 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) CCN(CC(=O)NCc1cccs1)C(=O)/C=C/c1cc(OC)ccc1OC
(b) O=C(O)[C@H]1CCCC[C@H]1C(=O)Nc1ccc(S(=O)(=O)N2CCOCC2)cc1
Answer: a. CCN(CC(=O)NCc1cccs1)C(=O)/C=C/c1cc(OC)ccc1OC
