. Consider the program segment:
x= 0; y=0;
Cobegin
begin
x= 1; y= y + x;
end
begin
y= 2; x= x + 3;
end
Coend;
Which of the following indicates possible values for the variables when the segment finishes execution?
(1) x= 1, y= 2 (2) x= 1, y= 3 (3) x= 4, y= 6 (a) 1 only (b) 1 & 2 only (c) 1 & 3 only (d) 2 & 3 only (e) 1, 2, 3
