Didn't complete MBA, what should I mention

Hi,
I studied MBA for 2 years from 2005-2007 and then couldn't complete my MBA due to some medical problem. In late 2007 when I was ok, I joined a mid sized market research firm as that firm was ok with graduates as well. I was working there for some time then shift to another company in 2010, then a third company in 2011 and worked there till 2016. All through this my work was above average and hence nobody asked me for MBA certificate and all through I was working based on my graduation (engineering) degree only. In between (in 2011) the MBA college I passed from got derecognized by AICTE and was closed. Hence there is no way I can complete my MBA now. However, if I want to include it in future, what should I do?
a) Studied MBA but didn't pass - mention it in CV?
b) Mention MBA completed in 2007 and explain that I have not passed it during the interview (first round)?
c) Do not mention MBA at all?
I am personally not in favor of option (c) as I do not want those 2 years of study to go waste.
Please advice.
Thanks.

Nobody have any interest to know about how many years you are wasted or not . If u don't have the certificate, you need not to mention it in your profile.
Further at the time of interview you can verbally describe the same that you studied MBA two years but due to medical problem you did not complete the same.

many of them are still working in HR from Engineering background. Don't worry there are many companies who grab the candidates who have knowledge and experience. Just mention them frankly about your situation, just like your past companies other companies will hire you and may not ask or required to know whether you have masters in MBA or no.
In India - Companies required Degrees and Reference not the real time knowledge and skills. Only Politics category follow this.. Whereas in America you can complete your graduation whenever you are interested and free to study. Studies shouldn't have age criteria.

Qualification is something that shows what you have learnt through books and course.Experience and skill aquired speak what you can actually do.Be the confident personility to offer best of your skills and experience to corporate inc.How ever I suggest to keep learning and adding value.

Unfortunately you have not completed MBA.
No point even mentioning it verbally in interviews/job discussions etc, forget about mentioning it in CV.
It is a sad part of life, but completed degree with certificate only has value.
