You can see from the above that only four whole numbers are there whose squares and cubes have the same number of digits
The parabola opens towards left, this means the squared term is y with negative coefficient.
The vertex is given to be the point (-1,-3). So, the general equation of the parabola will be like:

where a is any constant.
In the given options, only 1 such equation is available and that is option C.
So the answer to this question is option C
