Solution
The correct answer is c. i, iii.
Explanation:
i. "By default, only button-click events cause the form to be posted back to the server." This statement is correct. In web forms, a postback is the process of submitting an HTML form to the server for processing. By default, this happens when a button is clicked.
iii. "A postback is forced for events of that control when set the AutoPostBack property of a control true." This statement is also correct. The AutoPostBack property, when set to true, causes the form to be automatically posted back to the server whenever a specified event occurs, such as a change in a text box or a selection from a drop-down list.
