Task: Answer the multiple choice question.
Query: Which compound has a 5.683\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CCOC(=O)c1c(NC(=O)COC(=O)c2cnccn2)sc(C(=O)NC)c1C
b Cc1ccccc1NC(=O)/C(C#N)=C\c1ccsc1
Answer: a. CCOC(=O)c1c(NC(=O)COC(=O)c2cnccn2)sc(C(=O)NC)c1C
