In the given figure ABCD is a rectangle and the side lengths are integers. The perimeter of the rectangle is 48 and AB is parallel to the x-axis. If AB – BC < 4, which of the following can be the co-ordinate of C?
I. (16, 17)
II. (16, 15)
III. (17,16)
A. I only
B. II only
C. III only
D. I and III
E. I , II, andIII[/quote]

2*(AB+BC) =48..So, (AB+BC)=24...i.e., BC=24-AB..eqn 1
Given, AB-BC < 4
substituting eqn 1...
AB-(24-AB) < 4
AB<14.
Now, as sides are integers(given), max
