Let φ (x) = 
, where a 0 ≠ 0, b 0 ≠ 0 and m, n ∈ N, then which of the following statements is/are correct.
A
If m > n then, 
φ (x) is equal to 0
φ (x) is equal to 0
B
If m = n then, 
φ (x) is equal to 
φ (x) is equal to
C
If m < n and n – m is even, 
> 0, then 
φ (x) is equal to ∞
> 0, then φ (x) is equal to ∞
D
If m < n and n – m is even, 
< 0, then 
φ (x) is equal to – ∞
< 0, then φ (x) is equal to – ∞
