Ruby - String Operations

text = "world"
text[2] = 'r'
puts text

Aworrd

Bword

Cworld

Dworod

Step-by-Step Solution

Solution:

Step 1: Analyze the code
The string "world" has its character at index 2 replaced with 'r'.
Step 2: Identify index 2 character
Indexing starts at 0: w(0), o(1), r(2), l(3), d(4). The character at index 2 is 'r'. Replacing 'r' with 'r' keeps the string unchanged.
Step 3: Confirm the output
Since the character is replaced with the same letter, the string remains "world".
Final Answer:
world -> Option C
