Task: Answer the multiple-choice question.
Query: Which compound exhibits a -20.503% 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) O=C(NCCC1CCCCN1S(=O)(=O)c1ccccc1)C(=O)NCc1ccccc1
(b) C=CCn1c(O)c(C(CC)=Nc2ccc(N(C)C)cc2)c(=O)[nH]c1=O
Answer: a. O=C(NCCC1CCCCN1S(=O)(=O)c1ccccc1)C(=O)NCc1ccccc1
