To answer this question, you need to understand the concept of a Timer control.
The Timer control in programming is used to execute a piece of code at regular intervals. It allows you to perform a specific action repeatedly after a certain time interval.
The Timer control typically contains one event, which is the Tick event. The Tick event is triggered every time the specified interval elapses. You can write code in the Tick event handler to perform the desired action.
Based on this information, let's go through each option:
Option A) 1 - This option is correct. The Timer control contains one event, which is the Tick event.
Option B) 2 - This option is incorrect. The Timer control only contains the Tick event.
Option C) 3 - This option is incorrect. The Timer control only contains the Tick event.
Option D) 0 - This option is incorrect. The Timer control contains the Tick event.
Therefore, the correct answer is A) 1. The Timer control contains one event, which is the Tick event.
