The correct answer is: A. view menu.

The Object Browser is a tool in Visual Studio that allows you to view the objects and classes that are available in your project. You can open the Object Browser from the View menu or by pressing the key F2. The left column of the Object Browser lists the objects and classes that are available in the projects. The right column displays information about the selected object or class, such as its properties, methods, and events.

The other options are incorrect because:

• The Tool menu contains tools that are used to develop and debug your code.
• The Insert menu contains commands that are used to insert code into your project.
• The Object Browser is not a menu item.
