ANs: b. Output is 10.
bcoz in method afunction() allocates new memory to var x and
change its value after that, but tha actual variable doesn't
changes its location, thats why its remains same as it has
initialised by 10.
But if memory allocation by "new" has not ben done than it
will change the value as 12.
