Task: Answer the multiple-choice question.
Query: Which compound exhibits a -2.604\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(CCn1c(=O)oc2cc(Cl)ccc21)Nc1ccc(N2CCOCC2)cc1
[b] Cc1ccc2nc(N(CCN(C)C)C(=O)c3cc(Cl)sc3Cl)sc2c1.Cl
[c] O=C(Nc1ccc(F)c(F)c1)c1ccccc1-c1ccccc1
[d] COc1ccc(C(=O)OCCN2CCOCC2)cc1.Cl
Answer: c. O=C(Nc1ccc(F)c(F)c1)c1ccccc1-c1ccccc1
