Explanation / Answer

2)

Break statement :

Break statement  is used for terminate the program. So switch statement uses break statement to stop execution of the case statement after the break statement.

Option a is correct choice.

3)

Omission of variable declaration :

_dollar4me is a valid statement.

Hence option B is correct choice

4)

Option B : if(x>=0&&x<=50) is correct choice.

Reason :

From the question x value is between 0 and 50.

Since we use the && statement if both the conditions are TRUE then the if statement runs.

Here

condition 1 : The value of x is zero or greater than zero. Ex : 0,1,2,3....n

condition 2 : The value of x is fifty or less than zero. Ex : 50,49,48,.... - n.

So condition 1 and condition 2 is true when the numbers between 0 and 50.
