B Correct answer
Explanation

In Windows Forms, the ampersand (&) character before a letter creates an access key (shortcut). Writing "&Go" makes ALT+G trigger the button. The @ prefix in option A is for verbatim strings in C# and doesn't create shortcuts. Using && (option C) would display a literal ampersand. Option D uses @ incorrectly in this context.

AI explanation

To assign a shortcut to the button Bt1 so that the Click event is raised when the user presses ALT+G, you need to use the '&' character in the button's text. This character is used to define the shortcut key.

The correct code to assign the shortcut would be:

Bt1.Text = "&Go";

Option A) Bt1.Text = @”Go”; - This option is incorrect because it does not include the '&' character to define the shortcut key.

Option B) Bt1.Text = “&Go”; - This option is correct because it includes the '&' character to define the shortcut key as ALT+G.

Option C) Bt1.Text = “&&Go”; - This option is incorrect because it includes two '&' characters, which is not necessary and would not work as a shortcut key.

Option D) Bt1.Text = “@Go”; - This option is incorrect because it includes the '@' character, which is not used to define a shortcut key.

The correct answer is Option B.
