Task: Answer the multiple-choice question.
Question: Which compound exhibits a 8.675\% 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 or b without using any other words.
Options:
[a] Cc1oc(C)c2c(=O)ccc3c(c12)OC(N)=C(C#N)C3c1ccccc1Cl
[b] CC(C)(C)c1nnc2sc(SCCN3C(=O)c4ccccc4C3=O)nn2c1=O
Answer: a. Cc1oc(C)c2c(=O)ccc3c(c12)OC(N)=C(C#N)C3c1ccccc1Cl
