Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.982\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOc1ccccc1NC(=O)/C=C/c1ccccc1[N+](=O)[O-]
b: COC(=O)Nc1ccc(N2CCOCC2)c(S(=O)(=O)N2CCOCC2)c1
c: CC(C)NS(=O)(=O)c1ccc(OCC(=O)NCC2CCCO2)c(Cl)c1
d: CCC(CC)NC(=O)Nc1ccc(F)cc1F
Answer: a. CCOc1ccccc1NC(=O)/C=C/c1ccccc1[N+](=O)[O-]
