Is this question wrong? cuz I thought according to Kaplan book that ketal is when we do not have any H branch and acetal is when we have an H branch left as well as to OR and one R let me know what you think.

No its not wrong an acetal is a R-O-R-O-R group. Choice B is the answer. And again when asking a question like this post the entire question.

LOL copyright laws...

You can post the question if you do not post the answers. If they still have problems with that, just rephrase the question.

A tree is what?

lol...



As for the OPs question, the way I remember it, the acetal comes from a hemiacetal (+alcohol) which has an unreactive H group left, while the Ketal comes from a hemiketal which already has 2 R groups attached as well as the ether and OH.
