I would think it would be (A): #1# #"m/s"^2#.

Explanation:

In the image, it appears as if object B is inside of object A, so whatever acceleration object A has should be the exact same as that for object B...

Picture it like this:

If you are running at a constant speed of #4# #"m/s"#, then everything a part of you will also be traveling at #4# #"m/s"#...because where else could your heart, lungs, or brain go except with you?

See below.

Explanation:

Assuming that block B slides inside the cavity frictionless, block B acceleration is composed both of block A horizontal acceleration and this same acceleration downwards. So the resulting acceleration is #norm(1 i -1 j) = sqrt(2)# [m/#"s"^2#]
