Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.228\% 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(NCCC1CCCCN1S(=O)(=O)c1ccccc1)C(=O)NCc1ccccn1
(b) CC(=O)c1ccc(NC(=O)C[n+]2ccc(N(C)C)cc2)cc1.[Cl-]
(c) Cc1ccc2cc(-c3noc(C(C)(C)C)n3)c(=O)[nH]c2c1
Answer: a. O=C(NCCC1CCCCN1S(=O)(=O)c1ccccc1)C(=O)NCc1ccccn1
