Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.589\% 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, or c without using any other words.
Options:
a. CCc1cc(=O)[nH]c(SCCC(F)=C(F)F)n1
b. COc1ccc(S(=O)(=O)N2CCOC23CCN(S(=O)(=O)c2ccc(Cl)cc2)CC3)cc1
c. CNC(=O)CSc1nnc(-c2cccnc2)n1CCc1ccccc1
Answer: a. CCc1cc(=O)[nH]c(SCCC(F)=C(F)F)n1
