Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Dataverse table permissions were modified
Dataverse table permissions control whether data can be written to the tables. If these permissions were modified (e.g., accidentally removed write access), the form would fail to save data. Option A is incorrect because web roles affect authentication and access to pages, not directly the ability to submit data. Option C is incorrect because site visibility (public/private) only determines who can view the site, not data submission. Option D is incorrect because page permissions affect access to the page itself, not the form's ability to save data to Dataverse.
