Task: Answer the multiple-choice question.
Query: Which compound exhibits a 5.076\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(/C=C/Nc1ccccc1OC(F)(F)F)C(F)(F)F
[b] CCCCn1c(=O)[nH]c(=O)c2c1nc(CN(C)Cc1cccc(OC)c1OC)n2CCC.O=C(O)C(=O)O
[c] CCCCn1c(-c2ccccc2)cnc1SCC(=O)NCCc1ccc(OC)c(OC)c1.Cl
Answer: a. O=C(/C=C/Nc1ccccc1OC(F)(F)F)C(F)(F)F
