BWrong function name used
CPost ID should be a string
DMetadata key must be numeric
Step-by-Step Solution

    The function requires post ID, meta key, and meta value. The value is missing here.
  2. Step 2: Validate other options

  3. Final Answer:

    Missing the metadata value parameter -> Option A
  4. Quick Check:

    add_post_meta() needs value parameter [OK]
Quick Trick: add_post_meta() needs 3 parameters: ID, key, value [OK]
Common Mistakes:
  • Omitting the value parameter
  • Thinking post ID must be string
  • Assuming meta key must be numeric
