Task: Answer the multiple choice question.
Question: Which compound has a 24.508% 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 CC1=C(C(N)=O)C(c2cccs2)NC(=S)N1
b COC(=O)c1ccc(/C=C/c2c(-c3ccsc3)oc3ccc(N4CCOCC4)cc23)cc1
Answer: a. CC1=C(C(N)=O)C(c2cccs2)NC(=S)N1
