Best answer
Correct choice is (a) Elements, faces, nodes and neighbours

To explain: The data structure for an unstructured grid should contain information about the elements, faces, nodes and in addition to these about the neighbouring elements also. As they are not properly arranged, the neighbouring elements cannot be defined using indices.
