@rishu7865 In c language
A void pointer can point to objects of any data type:

However, because the void pointer does not know what type of object it is pointing to, it cannot be dereferenced directly! Rather, the void pointer must first be explicitly cast to another pointer type before it is dereferenced.
that why 3 option is the correct one
