Task: Answer the MCQ question.
Query: Which compound exhibits a -17.625% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] COC(=O)C1=C(CSc2nc3c(cc2C#N)CN(C)CC3)OC(N)=C(C#N)C1c1ccccc1F
[b] Cc1cc(C)n(/N=C/c2cc([N+](=O)[O-])ccc2O)c(=O)c1
Answer: a. COC(=O)C1=C(CSc2nc3c(cc2C#N)CN(C)CC3)OC(N)=C(C#N)C1c1ccccc1F
