Why does chaining multiple lazy enumerator methods not immediately execute the block code?

ABecause lazy enumerators convert to arrays before processing

BBecause Ruby caches all lazy enumerator results upfront

CBecause lazy enumerators build a chain of operations executed only when needed

DBecause blocks in lazy enumerators are ignored until .force is called

Step-by-Step Solution

Solution:

Step 1: Understand lazy enumerator execution model
Lazy enumerators create a chain of operations that are not executed until the result is requested.
Step 2: Evaluate other options
Ruby does not cache all results upfront; lazy enumerators do not convert to arrays automatically; blocks are not ignored but deferred.
Final Answer:
Because lazy enumerators build a chain of operations executed only when needed -> Option C
Quick Check:
Lazy enumerator execution = deferred chain execution [OK]

Quick Trick: Lazy chains run blocks only when output is requested [OK]
