Task: Answer the MCQ question.
Query: Which drug exhibits a 12.551% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C1Nc2ccccc2Nc2ncccc21
[b] N#CC1CC(c2ccccc2)=NN1c1ccccc1[N+](=O)[O-]
[c] CCOc1cccc(-c2c(C(=O)N/N=C/c3cccs3)nnn2-c2nonc2N)c1
Answer: b. N#CC1CC(c2ccccc2)=NN1c1ccccc1[N+](=O)[O-]
