can u solve please sir?

By considering different paths of approach, show that the function below has no limit as (x,y)→(0,0).
f(x,y)=
x4
OA. y=kx², x=0
OB. y=kx³, x 0
OC. y=kx, x#0
OD. y = kx + kx², x=0
If (x,y) approaches (0,0) along the curve when k = 1 used in the set of curves found above, what is the limit?
(Simplify your answer.)
If (x,y) approaches (0,0) along the curve when k = 0 used in the set of curves found above, what is the limit?
(Simplify your answer.)
What can you conclude?
O A. Since f has the same limit along two different paths to (0,0), in cannot be determined whether or not f has a limit as (x,y) approaches (0,0).
OB. Since f has the same limit along two different paths to (0,0), by the two-path test, f has no limit as (x,y) approaches (0,0).
OC. Since f has two different limits along two different paths to (0,0), in cannot be determined whether or not f has a limit as (x,y) approaches
O D. Since f has two different limits along two different paths to (0,0), by the two-path test, f has no limit as (x,y) approaches (0,0).
