Answer 2

Hi,

B.Reduces the size of the JavaScript  is your answer

Closure Compiler is used for reducing the size of JavaScipt file by  

1. replacing variable names with chars like a, b, c etc

2. removes white space form code

3. removes dead code

for example

function greetMe(name) {

 alert('Hello, ' + name);

}

greetMe('Ajay');

will become

function greetMe(a){alert("Hello, "+a)}greetMe("Ajay");
