Match the following:

Column I	Column II
1. The difference of the greatest negative integer and smallest positive integer is	-4
2. The sum of additive inverse is	-2
3. The sum of predecessor and successor of 1 is	0
4. The additive inverse of 4 is	1

(1) -4, (2) 0, (3) 2, (4) 1

(1) -2, (2) 0, (3) 1, (4) -4

(1) 0, (2) 1, (3) -2, (4) -4

None of these
