3. Final Answer:

   blog -> Option D

4. Quick Check:

   Project folder = last argument 'blog' [OK]

Hint: Last word in command is your app folder name [OK]

Common Mistakes:

Solution

1. Step 1: Check default behavior of create-project

   If no folder name is given, Composer uses the package name as the folder.

2. Step 2: Apply to Laravel package

   Since the package is laravel/laravel, it creates a folder named laravel.

3. Final Answer:

   Laravel installs in a folder named 'laravel' -> Option C

4. Quick Check:

   No folder name defaults to package name folder [OK]

Hint: No folder name? Uses package name as folder [OK]
