Task: Answer the multiple choice question.
Query: Which compound has a 3.919% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1ccc(CCNC(=O)COC(=O)C23CC4CC(CC(C4)C2)C3)cc1
(b) O=C(NC(Cc1c[nH]c2ccccc12)c1nnc2n1CCCCC2)c1ccccc1
(c) CCOc1ccc(CCNS(=O)(=O)c2c(C)n[nH]c2C)cc1OCC
(d) Cc1ccc(C2=NN(C(=O)CCC(=O)O)C(c3cn(-c4ccccc4)nc3-c3ccc(C)cc3)C2)cc1
Answer: c. CCOc1ccc(CCNS(=O)(=O)c2c(C)n[nH]c2C)cc1OCC
