Answer: I a reference to the next node
III a data element
Explanation:
A linked list is simply referred to as a linear data structure, whereby the elements would not be stored at memory locations that are together in the sequence.

Therefore, based on the explanation above, the correct option will be:
I. a reference to the next node
III a data element
