The technique for overcoming external fragmentation is A. compaction.

Here's a step-by-step explanation:

1. Fragmentation occurs when memory is allocated and deallocated in such a way that free memory is divided into separate blocks. This can be internal (within a process's allocated memory) or external (between processes).

2. External fragmentation happens when free memory blocks are scattered and not contiguous. Even if the total free memory is enough to satisfy a request, it may not be in one contiguous block, which can prevent the request from being fulfilled.

3. Compaction is a technique used to overcome this. It works by moving all the free memory blocks to one contiguous block and all the allocated memory to another. This makes it much easier to allocate memory to processes as they can be given one large block rather than several smaller ones.

4. Therefore, the answer is A. compaction.
