What will be the output of the following Ruby code?

def test_proc
  p = Proc.new { return "From Proc" }
  p.call
  return "From method"
end

puts test_proc

A"From Proc"

B"From method"

Cnil

DRuntimeError

Step-by-Step Solution

Solution:

Step 1: Understand Proc return behavior
When a Proc executes a return, it returns from the enclosing method, not just the Proc block.
Step 2: Trace the code execution
Calling p.call triggers the Proc's return, which exits the test_proc method immediately with "From Proc". The later return "From method" is never reached.
Final Answer:
"From Proc" -> Option A
Quick Check:
Proc return exits method = "From Proc" [OK]

Quick Trick: Proc return exits method; lambda return exits lambda only [OK]
