Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.221\% 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. CC(C)CC1=NC(C(F)(F)F)(C(F)(F)F)c2c(n(CC(C)C)c(=O)[nH]c2=O)N1
b. O=C(Nc1cnccn1)Nc1ccc(Cl)cc1Cl
c. COc1cccc(NC(=O)N2CCN(c3ccc(C(F)(F)F)cn3)CC2)c1
Answer: a. CC(C)CC1=NC(C(F)(F)F)(C(F)(F)F)c2c(n(CC(C)C)c(=O)[nH]c2=O)N1
