Problem statement: Answer the multiple choice question.
Query: Which compound has a -0.027\% 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) COC(=O)C1=C(C)N(CCCC(=O)O)C(=O)NC1c1ccc(C#N)cc1
(b) O=C(CN1CCCCCC1)NC(c1ccccc1)c1ccccc1.O=C(O)C(=O)O
(c) CCNC(=O)CSc1nnc(-c2ccc(OC)cc2)n1CC(C)C
Answer: a. COC(=O)C1=C(C)N(CCCC(=O)O)C(=O)NC1c1ccc(C#N)cc1
