Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.080\% 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 S=c1[nH]nc(-c2ccco2)n1/N=C/c1ccc(Cl)cc1Cl
b COc1ccc(S(=O)(=O)N(CC(=O)NCCSc2ccccn2)c2ccccc2)cc1
c O=C(CN(c1cccc(C(F)(F)F)c1)S(=O)(=O)c1ccc(Cl)c([N+](=O)[O-])c1)NCc1ccccc1Cl
d CCn1c(=NC(=O)CS(=O)(=O)c2ccc(C)cc2)sc2cccc(OC)c21
Answer: c. O=C(CN(c1cccc(C(F)(F)F)c1)S(=O)(=O)c1ccc(Cl)c([N+](=O)[O-])c1)NCc1ccccc1Cl
