Answer should be A & B. Explanation is given below

Option A
MemFree = completely unused physical RAM
This memory is immediately available and is not used by the system or processes

Option B
Cached = I/O cache (filesystem cache)
Used to Speed up disk access and Can be freed automatically when needed

Option C is wrong
“98908 kB of memory that will never be used”
This refers to Inactive: 98908 kB. This is incorrect because Inactive memory can be reused. It is not permanently unusable

Option D is wrong
“Unused cache page represented by Inactive”
Inactive ≠ unused cache only It includes Cached pages and Memory not recently used
