Explanation:

In the periodic table, elements are represented by one - or two - letter symbols. For example, hydrogen is H and oxygen is O. Elements are not ordered alphabetically, not just abbreviations of first letters of names (as some symbols come from Latin names), and not ordered by discovery time in terms of representation in the box.

Answer:

D. Each element is represented by a one or two - letter symbol.
