A13

B15

C12

D14

Step-by-Step Solution

Solution:

Step 1: Analyze the original string length
The string " Hello World! " has 16 characters including spaces (2 spaces left, 12 characters in "Hello World!", 2 spaces right).
Step 2: Apply rtrim() and measure length
rtrim() removes spaces from the right only, so 2 spaces on the right are removed. The length becomes 16 - 2 = 14 characters.
Step 3: Confirm the output
The code outputs 14.
Final Answer:
14 -> Option D
Quick Check:
rtrim() removes right spaces, length = 14 [OK]

Quick Trick: rtrim() removes right spaces, length decreases accordingly [OK]
