Solution (By Examveda Team)

This question asks about stored programs in MySQL. Stored programs are like mini-programs that live inside your database, making your code more efficient and reusable.

The question lists four types of stored objects:
* Functions: Like regular functions in programming, they perform tasks and return a value.
* Procedures: Similar to functions but don't have to return a value. They can be used to perform complex actions.
* Triggers: Automatically run when a specific event happens in your database, like inserting, updating, or deleting data.
* Events: Scheduled tasks that run at specific times or intervals.

Now, let's see which of these are stored programs. All of them are! They're all stored objects that contain code and are executed within the database.

So the answer is Option D: 4.
