What will be the output of this Ruby code?

def merge_and_sort(*arrays)
  arrays.flatten.sort
end

p merge_and_sort([5, 3], [1, 4], [2])

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

B[[5, 3], [1, 4], [2]]

C[1, 2, 3, 4, 5]

D[1, 3, 4, 5]

Step-by-Step Solution

Solution:

Step 1: Understand the method
The method accepts any number of arrays, flattens them into one array, then sorts the elements.
Step 2: Flatten the arrays
Input arrays: [5, 3], [1, 4], [2] flatten to [5, 3, 1, 4, 2].
Step 3: Sort the flattened array
Sorted array is [1, 2, 3, 4, 5].
Final Answer:
[1, 2, 3, 4, 5] -> Option C
Quick Check:
Flatten then sort arrays [OK]

Quick Trick: Flatten arrays before sorting to combine elements [OK]
