IMM1294E – Confusion about level of study [Fanshawe ISM]

I got offer letter form Fanshawe College – Information Security Management. This is a One-Year Ontario College Graduate Certificate Program. While filling the IMM1294E, I became bit confused. In my LOA Level of study is “post graduate program”. There is three option in IMM194E about the level of study. It’s a College-Certificate,College-Diploma,College-Applied Degree. Now, which one should I choose?

Thank you.
