Ruby - Blocks, Procs, and Lambdas

How can you modify this Ruby code to create closures that each remember a different value of i even if i changes later?

closures = []
3.times do |i|
  closures << lambda { i }
end
closures.each { |c| puts c.call }

ACall closures inside the times block

BChange lambda to proc

CUse global variable $i instead of i

DUse a local variable inside the block to capture i: <code>val = i; closures << lambda { val }</code>

Step-by-Step Solution

Solution:

Step 1: Understand variable capture in closures
Closures capture variables by reference, so if i changes later, all lambdas see the last value.
Step 2: Use a local variable to capture current value
Assign val = i inside the block, then create lambda using val. This captures the value at that iteration.
Final Answer:
Use a local variable inside the block to capture i: val = i; closures << lambda { val } -> Option D
Quick Check:
Capture current value with local variable [OK]

Quick Trick: Assign loop variable to local var inside block for closure [OK]
