Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.766\% 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] Cc1ccc(-n2nnnc2SCn2nnc3ccccc3c2=O)cc1
[b] COc1ccc(C2C(C#N)=C(SC)NC3=C2C(=O)CC(C)(C)C3)cc1
[c] Cc1cc(C)cc(Nc2c(F)c(F)c(F)c(F)c2C(=O)O)c1
Answer: b. COc1ccc(C2C(C#N)=C(SC)NC3=C2C(=O)CC(C)(C)C3)cc1
