Step-by-Step Solution

Solution:

Step 1: Analyze file opening and writing
The file 'test.txt' is opened in write mode, then "Hello World" is written to it, and the file is closed.
Step 2: Read and output file contents
file_get_contents reads the file content, which now contains "Hello World", so echo prints it.
Final Answer:
Hello World -> Option C
Quick Check:
Write then read file = Hello World [OK]

Quick Trick: Write then read file outputs written text [OK]
