The class DArray has three private member variables: int *arr; //will point to a dynamic array of integers int capacity; //capacity of the array int numfElements; //total number of elements in the a rray Given the header of the member function overwrite, as shown below, which implementation would correctly overwrite the last element of the parameter object with the first element of the calling object? void Darray:: overwrite(const Darray& other rray) const { // implementation } otherArray->arr[numOfElements - 1] = arr[0]; otherArray[numOfElements - 1] = arr[0]; arr.otherArray[numOfElements - 1] = arr[0]; otherArray.arr[numOfElements - 1] = arr[0]; O None of the above
