  "@type": "Person",
  "name": "Alice Smith",
  "jobTitle": "Software Engineer"

   @context, @type, and name are present and correct.

3. Final Answer:

   Invalid month value in startDate -> Option A

4. Quick Check:

   "Product" is for items sold, "Article" is for written content, and "Event" is for happenings, so they don't fit.

3. Final Answer:

   Recipe -> Option A

4. Quick Check:
