Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.715\% 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=c1c(-c2ncc(C(F)(F)F)cc2Cl)c[nH]c2ccc(Cl)cc12
b. O=C(COC(=O)c1ccc(S(=O)(=O)N2CCCC2)cc1)NCc1ccc(F)cc1
c. O=C(Nc1ccc(Cl)cc1)c1ccc2c(c1)S(=O)(=O)c1ccccc1C2=O
Answer: a. O=c1c(-c2ncc(C(F)(F)F)cc2Cl)c[nH]c2ccc(Cl)cc12
