Answer:

A) Switch

Explanation:

In Java and most programming Languages, A Switch Statement provides a multi branch statements which provides a more flexible way for transfer of execution to the branch that fulfills the condition of the expressed value. This is a better way of handling if...elseif....else statements. In this way, a variable is tested for equality against some values. Variables used in switch expressions can only be primitives (int, byte, char), enums and strings.  A switch statement has

1. A default statement (optional), appears at the end of the switch and acts as the else condition.

2. A break statement which terminates the switch when reached.

The syntax of a switch statement is given below:

switch(expression) {

 case x:

   // code block

   break;

 case y:

   // code block

   break;

 default:

   // code block
