Explanation:
Telescope is an instrument used to measure vertical and horizontal angles in surveying. The telescope is said to be inverted if the vertical circle is to its right and the bubble of the telescope is down. Let's understand this in detail.

Vertical Circle:
A vertical circle is a circle that passes through the zenith and the nadir points of a station. It is perpendicular to the horizontal plane and is used to measure vertical angles.

Bubble of the Telescope:
The bubble of the telescope is a small vial filled with liquid that is mounted on the telescope. It is used to determine whether the telescope is level or not. If the bubble is centered between two lines on the vial, the telescope is level.

Inverted Telescope:
Now, let's understand why an inverted telescope has the vertical circle to its right and the bubble of the telescope is down. When the telescope is inverted, the eyepiece is facing downwards, and the objective lens is facing upwards.

- The vertical circle is placed on the right side of the telescope to make it easy for the surveyor to read the measurements while looking through the eyepiece. If the vertical circle was placed on the left side, the surveyor would have to look over the telescope to read the measurements, which is not convenient.
- The bubble of the telescope is down in an inverted telescope because the level of the telescope is opposite to the normal position. In a normal telescope, the bubble is up when the telescope is level. But in an inverted telescope, the bubble is down when the telescope is level.

So, option A is the correct answer.
