Ruby - Concurrent Programming

What feature does a Fiber provide in Ruby's concurrency model?

AEnables asynchronous I/O operations without blocking

BAutomatically manages multiple threads in parallel

CAllows pausing and resuming code execution explicitly

DCreates new processes for parallel execution

Step-by-Step Solution

Solution:

Step 1: Understand Fiber's role
Fibers provide cooperative concurrency by allowing code to pause and resume explicitly.
Step 2: Differentiate from threads and processes
Unlike threads or processes, Fibers do not run in parallel automatically.
Final Answer:
Allows pausing and resuming code execution explicitly -> Option C
Quick Check:
Fibers are cooperative, not preemptive concurrency [OK]

Quick Trick: Fibers pause and resume code manually [OK]
