Aapp.mount('/photos', StaticFiles(directory='images'), name='photos') app.mount('/js_files', StaticFiles(directory='scripts'), name='js_files')

Bapp.mount('/images', StaticFiles(directory='photos'), name='images') app.mount('/scripts', StaticFiles(directory='js_files'), name='scripts')

Capp.mount('/images', StaticFiles('photos')) app.mount('/scripts', StaticFiles('js_files'))

Dapp.mount('/images', StaticFiles(directory='photos')) app.mount('/scripts', StaticFiles(directory='js_files'))

Step-by-Step Solution

Solution:

Step 1: Verify mount paths and directories
The URL paths must match the desired endpoints: '/images' and '/scripts'.
Step 2: Check directory arguments
Directories must correspond to the folders: 'photos' and 'js_files'.
Step 3: Name parameter
Providing a name is recommended for clarity and routing.
Step 4: Analyze options
app.mount('/images', StaticFiles(directory='photos'), name='images') app.mount('/scripts', StaticFiles(directory='js_files'), name='scripts') correctly matches URL paths, directories, and includes names.
Final Answer:
app.mount('/images', StaticFiles(directory='photos'), name='images') app.mount('/scripts', StaticFiles(directory='js_files'), name='scripts') -> Option B
