Ruby - Blocks, Procs, and Lambdas

Given this code, what will be the output?

pairs = [[1, 2], [3, 4], [5, 6]]
pairs.each do |a, b|
  puts a + b
end

A[1, 2] [3, 4] [5, 6]

B3 7 11

CError: wrong number of block parameters

D1 3 5

Step-by-Step Solution

Solution:

Step 1: Understand multiple block parameters
The block parameters a and b receive each inner array's two elements separately.
Step 2: Calculate sum for each pair
For each pair, the code prints the sum: 1+2=3, 3+4=7, 5+6=11.
Final Answer:
3 7 11 -> Option B
Quick Check:
Sum of pairs = 3,7,11 [OK]

Quick Trick: Use multiple block parameters to unpack arrays inside each [OK]
