Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.333\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CCOC(=O)NC(=O)CSc1nc(C)cc(C(F)(F)F)c1C#N
b O=C(COC(=O)/C=C/c1cccc(Cl)c1)NC(=O)NCc1ccccc1
c O=C(Nc1ccccn1)c1ccc(=O)[nH]n1
d COc1cc(/C=C(\NC(C)=O)C(=O)Nc2ccccc2C)ccc1OC(C)=O
Answer: a. CCOC(=O)NC(=O)CSc1nc(C)cc(C(F)(F)F)c1C#N
