Answer:
the counting numbers and zero are whole numbers.
the counting numbers and their opposites, along with zero, are integers.

The diagram that shows all the lines of symmetry is diagram B.
<h3>
Which diagram shows all the lines of symmetry of the regular hexagon?</h3>
We define a line of symmetry as a line such that if we perform a reflection over that line, the <em>image coincides with the preimage </em>(so the reflection does not change the figure).
<em />
With that in mind, any line that cuts the hexagon in exactly two halves is a line of symmetry.
So the image that shows all the lines of symmetry of the regular is B, where it shows all the lines that cut the hexagon in two equal halves.
