Solution:
Step 1: Identify headers for validation and caching
ETag provides validation token; Cache-Control sets caching rules.Step 2: Confirm headers that enable efficient caching
ETag with Cache-Control max-age allows client to cache and validate efficiently.Final Answer:
ETag and Cache-Control: max-age=3600 -> Option DQuick Check:
ETag + Cache-Control enable validation caching = B [OK]
