Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.725\% human ether-à-go-go related gene (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(COn1nnc2ccc(C(F)(F)F)cc21)Nc1c(Cl)cccc1Cl
[b] O=C(CCN=C1NS(=O)(=O)c2ccccc21)OCc1cccc(Cl)c1
[c] O=C(Cn1nc(-c2cccc(Cl)c2)ccc1=O)Nc1cccnc1
[d] Cc1ccc(-c2c(C)sc3ncn(CC(=O)N4CCOCC4)c(=O)c23)cc1C
Answer: c. O=C(Cn1nc(-c2cccc(Cl)c2)ccc1=O)Nc1cccnc1
