Task: Answer the multiple choice question.
Question: Which compound has a 12.243\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCN1C(=O)/C(=C/N(C)c2ccccc2)OC1=S
b: COc1cc(NC(=O)COc2cc3oc(=O)cc(C)c3cc2Cl)cc(OC)c1OC
c: OC(CCc1ccncc1)c1ccccc1
Answer: a. CCN1C(=O)/C(=C/N(C)c2ccccc2)OC1=S
