(A) Got the Exception 10
(B) Got the Exception 0

Answer: (C)
Explanation: In Java only throwable objects (Throwable objects are instances of any subclass of the Throwable class) can be thrown as exception. So basic data type can no be thrown at all.
Following are errors in the above program
Main.java:4: error: incompatible types
throw 10;
^
required: Throwable
found: int
Main.java:6: error: unexpected type
catch(int e) {
^
required: class
found: int
