What will be the output of the following Ruby code?

fiber = Fiber.new do
  puts 'Step 1'
  Fiber.yield
  puts 'Step 2'
end

fiber.resume

fiber.resume

AStep 2 Between Step 1

BStep 1 Step 2 Between

CBetween Step 1 Step 2

DStep 1 Between Step 2

Step-by-Step Solution

Solution:

Step 1: Trace first resume call
Calling fiber.resume runs until Fiber.yield, printing 'Step 1'.
Step 2: Trace code after first resume
After yield, control returns to main, printing 'Between'.
Step 3: Trace second resume call
Second fiber.resume resumes after yield, printing 'Step 2'.
Final Answer:
Step 1 Between Step 2 -> Option D
Quick Check:
Fiber.yield pauses, resume continues [OK]

Quick Trick: Fiber.yield pauses; resume continues after yield [OK]
