DBecause safe methods require authentication every time

Step-by-Step Solution

Solution:

Step 1: Define safe methods in REST
Safe methods do not modify server data, so they can be repeated safely.
Step 2: Explain importance for caching and idempotency
Since safe methods don't change state, responses can be cached and repeated calls won't cause side effects.
Final Answer:
Because safe methods do not change server state, enabling caching and repeated calls without side effects -> Option A
Quick Check:
Safe methods enable caching and idempotency [OK]

Quick Trick: Safe methods allow caching and safe retries [OK]
