Given this code, what will be printed?

def test
  p = Proc.new { |x| return x * 2 }
  result = p.call(4)
  puts "After Proc call"
  result
end
puts test

AOnly 8

B"After Proc call" and then 8

C8 and then "After Proc call"

DOnly "After Proc call"

Step-by-Step Solution

Solution:

Step 1: Analyze Proc return effect
The return inside the Proc causes the entire method to return immediately with 8 (4 * 2).
Step 2: Check if code after Proc call runs
The line puts "After Proc call" is never executed because the method has already returned.
Final Answer:
Only 8 -> Option A
Quick Check:
Proc return exits method immediately = A [OK]

Quick Trick: Proc return exits method before later code runs [OK]
