   Other options are incorrect because they are not valid commands or miss the --version flag.

3. Final Answer:

   django-admin --version -> Option D

4. Quick Check:

   django-admin --version = A [OK]

Hint: Use 'django-admin --version' to check Django version [OK]

   The command python -m django --version outputs only the version number, e.g., '4.2'.

2. Step 2: Match output to options

   Only 4.2 matches the expected plain version number output.

3. Final Answer:

   4.2 -> Option A

4. Quick Check:

   python -m django --version = 4.2 [OK]

Hint: Version command outputs just the number like '4.2' [OK]

   Creating a virtual environment isolates packages per project, avoiding conflicts.

3. Step 3: Install Django inside the virtual environment

   Run pip install django inside the virtual environment to keep dependencies separate.

4. Final Answer:

   Create a virtual environment and run pip install django inside it -> Option B
