Explanation

A stack is called a LIFO (Last In, First Out) structure because the last element added is always the first one removed - like a stack of plates where you take from the top.

B (FIFO) - "First In, First Out" - describes a queue, not a stack; think of a line at a checkout where the first person in is the first served.

C (FOLO) and D (FIDO) are nonsense acronyms that don't correspond to any real data structure terminology.

Memory tip: Think of a stack of pancakes - you always eat (remove) from the top, which is the last one added. "Last pancake on, first pancake eaten" = LIFO.
