A'default': {'BACKEND': 'django.core.cache.backends.locmem.LocMemCache'}

B'default': {'BACKEND': 'django.core.cache.backends.filebased.FileBasedCache', 'LOCATION': '/var/tmp/django_cache'}

C'default': {'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1:11211'}

D'default': {'BACKEND': 'django.core.cache.backends.db.DatabaseCache', 'LOCATION': 'my_cache_table'}

Step-by-Step Solution

Solution:

Step 1: Identify the in-memory cache backend
The in-memory cache backend in Django is LocMemCache, which stores cache in local memory.
Step 2: Match the correct syntax
'default': {'BACKEND': 'django.core.cache.backends.locmem.LocMemCache'} correctly sets BACKEND to django.core.cache.backends.locmem.LocMemCache without needing a LOCATION.
Final Answer:
'default': {'BACKEND': 'django.core.cache.backends.locmem.LocMemCache'} -> Option A
Quick Check:
In-memory cache = LocMemCache [OK]

Quick Trick: LocMemCache is in-memory, no location needed [OK]
