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
✓
'before query'
The correct event to modify query conditions before a query runs is 'before query'. This event fires before the database query is executed, allowing the developer to modify the query condition. Option A ('before insert') is for record insertion, not queries. Option B ('after query') fires after the query, so it is too late to modify conditions. Option C ('display') is related to form rendering, not queries.
