Task: Answer the multiple choice question.
Question: Which drug exhibits a 21.057\% 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 other words.
Options:
a. Nc1cc(=O)[nH]c(=S)n1-c1cccc(C(F)(F)F)c1
b. COc1cc(CC(C)N)c(OC)cc1I.Cl
c. CCn1c(C)nc2cc(C(=O)NNC(=S)NC(=O)c3ccc(OC)cc3)ccc21
Answer: a. Nc1cc(=O)[nH]c(=S)n1-c1cccc(C(F)(F)F)c1
