Task: Answer the multiple choice question.
Query: Which drug exhibits a 26.273% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C1N=C(N2CCCC2)S/C1=C\c1cn[nH]c1-c1ccccc1
(b) CCCNC(=O)Cn1c(=O)cnc2ccccc21
(c) CN(C)C(=O)CSc1nnc(Cc2ccc([N+](=O)[O-])cc2)o1
Answer: b. CCCNC(=O)Cn1c(=O)cnc2ccccc21
