Task: Answer the multiple choice question.
Question: Which compound has a 19.055% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) CN=C1SC(C(=O)O)CC(=O)N1C
b.) COc1ccc(CCN=C(N)C(C)c2ccccc2)cc1OC.Cl
c.) CNC(=S)NNC(=O)Cc1ccc(OC)c(OC)c1
Answer: a. CN=C1SC(C(=O)O)CC(=O)N1C
