Answer to Question 1

C

Answer to Question 2

One reason is there are countless nonprofessional developers designing commercial Web applications. In addition to this, there are four other important contributing factors 1. The Web's single click-to-act method of loading static hypertext documents. 2. Limited capabilities of most Web browsers to support finely grained user interactivity. 3. Limited agreed-upon standards for encoding Web content and control mechanisms. 4. Lack of maturity of Web scripting and programming languages as well as limitations in commonly used Web GUI component libraries.
