Because cases fall-through to the next case unless you use the break statement.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
if "break;" statement is used then UR expected option B will be the result

so you mean after printing Zero the program doesn`t check if
case (2 == x) and it will print anything after case 0
No it doesn't.
The switch condition is only checked once, and that decides where in the switch statement the program jumps to. After that, the code just executes in a linear fashion like any other code until it comes to the closing brace or a break statement.
