The correct options are
A 3
B 2
D 6
Integers between -2 and 6 are -1, 0, 1, 2, 3, 4, 5
Since the set of whole numbers starts with 0, no negative number will be included and therefore the whole numbers between -2 and 6 are 0, 1, 2, 3, 4 and 5.
Hence, the number of whole numbers between -2 and 6 is 6.
