Task: Answer the multiple choice question.
Query: Which compound has a 3.381\% 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) CCOc1ccc(CCNC(=O)C2CCN(c3nnc(-n4cccc4)s3)CC2)cc1OCC
(b) O=C(Nc1ncc([N+](=O)[O-])s1)c1ccc2c(c1)OCO2
(c) CCCCN(Cc1cc2ccccc2[nH]c1=O)C(=O)c1ccccn1
Answer: b. O=C(Nc1ncc([N+](=O)[O-])s1)c1ccc2c(c1)OCO2
