"I was told"

So help me translate this phrase that keeps appearing in ads....

"I was told" ..... means:

A. I really don't know and I don't want to research for myself

B. It's just something sellers say, so to be cool I will say it too

C. I do know but I don't want to say and would rather be vague in hopes that I'll get more money for the item im selling

D. None of the above, so tell me
