1. a - JavaScript is embedded in HTML code, which runs on the client's machine.
2. c - You want strict control of sensitive data.
3. b - Web Servers do not allow public access to server-side scripts, if they did, hackers could find loop holes in the system, i.e. A client inputs JS into an HTML form. That data goes into the database and then into an served HTML page. The data is actually malicious JS code. Or, the client initiates a SQL injection attack, because he or she knows it will work with your code.
4. d - My best guess.
