- <u>Third choice: {3, 4, 6, 7, 9}</u>
Explanation:
<em>M ∪ N</em> means the union of the segments M and N. That is, the complete list of objects that are either in the set M or N.

The circle on the right of the diagram shows that the elements inside the set N are 4, 6 and 7.
The complete list of the numbers in either M or N is 3, 4, 6, 7, and 9 (you must not repeat the elements that belong to both sets but indicate them just once.
So, the set that represents M ∪ N is the third option {3, 4, 6, 7, 9}.
