The correct answer is "A could be decidable or undecidable. It depends on what A and B are."

Here's why:

In the context of computational theory, a problem (or set) A is said to be "decidable" if there exists some algorithm that can always solve instances of the problem in a finite amount of time.

If A ≤ B, this means that A is reducible to B. In other words, any instance of problem A can be "translated" into an instance of problem B. If B is decidable, this means there is an algorithm that can solve any instance of B.

However, just because A can be translated into B, this does not necessarily mean that A is also decidable. It's possible that the "translation" process itself is not decidable. Therefore, without additional information about what A and B are, we cannot definitively say whether A is decidable or undecidable.
