Task: Answer the multiple-choice question.
Query: Which compound exhibits a -7.907\% 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: C=CCn1c(SCC(=O)c2c(N)n(C)c(=O)n(C)c2=O)nc2sc(CC)cc2c1=O
b: O=c1c2ccccc2nc(-c2ccc(Cl)cc2Cl)n1O
c: O=C(COC(=O)c1ccc([N+](=O)[O-])o1)Nc1cccc(S(=O)(=O)N2CCOCC2)c1
Answer: a. C=CCn1c(SCC(=O)c2c(N)n(C)c(=O)n(C)c2=O)nc2sc(CC)cc2c1=O
