(a) External Fragmentation exists when there is enough total memory space to satisfy a request but the available space is contiguous.
(b) Memory Fragmentation can be internal as well as external.
(c) One solution to external Fragmentation is compaction.
Code:
(A) (a) and (b) only
(B) (a) and (c) only
(C) (b) and (c) only
(D) (a), (b) and (c)

Answer: (C)
Explanation:

External Fragmentation exists when there is enough total memory space to satisfy a request but the available space is contiguous. This is a false statement because external fragmentation occurs due to non contigious available space.
