Task: Answer the multiple choice question.
Query: Which compound has a 11.091\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(NCCc1ccco1)C(=O)NCC1OCCCN1S(=O)(=O)c1ccccc1
(b) O=C(CSc1ccc([N+](=O)[O-])cn1)Nc1ccc2c(c1)OCCO2
(c) CCCCN(C(=O)CSCc1c(C)noc1C)c1c(N)n(CCCC)c(=O)[nH]c1=O
Answer: b. O=C(CSc1ccc([N+](=O)[O-])cn1)Nc1ccc2c(c1)OCCO2
