option A is correct any doubt, plz ask, we will discuss
...
you can also take y = mx³ but its goes to infinity at numerator which is also 0
we take that value of y (or m) which satisfy the condition (0,0)
or aim to eliminate the variable from x (or y)
generally we take different path , but according to question
ohk, Thank you 😊
