AI Explanation

To answer this question, let's understand the IsPostBack property in the context of web development.

The IsPostBack property is commonly used in web development frameworks, such as ASP.NET, to determine whether a web page is being loaded for the first time or if it is a postback (i.e., a form submission or a server-side event triggered by a control).

The IsPostBack property returns a boolean value indicating whether the current request is a postback or not. In other words, it returns true if the page is being loaded as a result of a postback and false if it is the initial page load.

Now, let's go through each option to understand why it is correct or incorrect:

Option A) bit - This option is incorrect because the IsPostBack property does not return a bit data type. It returns a boolean value.

Option B) boolean - This option is correct because the IsPostBack property returns a boolean value indicating whether the current request is a postback or not.

Option C) int - This option is incorrect because the IsPostBack property does not return an int data type. It returns a boolean value.

Option D) string - This option is incorrect because the correct answer is not string. The IsPostBack property does not return a string data type.

Therefore, the correct answer is B) boolean. This option is correct because the IsPostBack property returns a boolean value indicating whether the current request is a postback or not.
