Explanation:

- The radius of the circle is 5 m.

- Chords AB and CD are equal and parallel with lengths of 8 m each.

- Since the chords are equal and parallel, their perpendicular distances from the center are equal.

To find the distance from the center to a chord, use the formula:

$$h=\sqrt{r^2-(l/2{)}^2}$$

where $r$ is the radius and $l$ is the length of the chord.

- For each chord:

- $h=\sqrt{5^2-(8/2{)}^2}=\sqrt{25-16}=\sqrt{9}=3m$

- The total distance between the chords is:

- $3m+3m=6m$

- The correct option is: Option 2: 6 m
