Correct Answer

A

Explanation

The statement that a terrestrial telescope has one extra lens more than an astronomical telescope is not accurate. In fact, astronomical telescopes typically have more lenses or optical elements than terrestrial telescopes, not the other way around.

Terrestrial telescopes are designed for observing objects on Earth, such as landscapes, animals, or buildings. They usually have a simple optical design with fewer lenses to provide an upright and correctly oriented image. This makes them suitable for terrestrial viewing where the orientation of the image matters.

Astronomical telescopes, on the other hand, are optimized for viewing celestial objects like stars, planets, and galaxies. They often have more complex optical systems with multiple lenses or mirrors to gather and magnify light, and they don't prioritize the orientation of the image since it's not critical in astronomy.

So, if you hear about an extra lens in a telescope, it's more likely to be found in an astronomical telescope, not a terrestrial one.
