Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.488\% 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. COc1ccc(S(=O)(=O)NCC2CCCO2)cc1NC(=O)c1ccc(Cl)cc1
b. COc1cc(/C=C2/C(=O)N(c3ccc(C)c(C)c3)N=C2C)cc([N+](=O)[O-])c1O
c. Cn1c(=O)c2nc(NNC(=O)c3ccccc3)cnc2n(C)c1=O
Answer: b. COc1cc(/C=C2/C(=O)N(c3ccc(C)c(C)c3)N=C2C)cc([N+](=O)[O-])c1O
