Given below are two statements: Statements 1: Astronomical unit (AU), Parsec (pc) and Light year (ly) are units for measuring astronomical distances. Statement 2: The light of the above distances, choose the most appropriate answer from the options given below:
Show Hint
Remember the standard units used in astronomy: AU for distances within the solar system, parsecs for larger distances, and light years for even larger distances.
Statement I is correct but Statement II is incorrect.

Verified By Collegedunia
The Correct Option isA
Solution and Explanation
- The astronomical unit (AU) is the average distance from the Earth to the Sun, the parsec (pc) is the distance at which one astronomical unit subtends an angle of one second of arc, and the light year (ly) is the distance that light travels in one year.
- These units are commonly used in astronomy to measure large distances in space.
Thus, both statements are correct.
