Given below are two statements :
Statement I : Astronomical unit (Au), Parsec (Pc) and Light year (ly) are units for measuring astronomical distances.
Statement II : Au < Parsec (Pc) < ly
In the light of the above statements, choose the most appropriate answer from the options given below:
Statement I : Astronomical unit (Au), Parsec (Pc) and Light year (ly) are units for measuring astronomical distances.
Statement II : Au < Parsec (Pc) < ly
In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth Statements I and Statements II are incorrect
- BStatements I is correct but Statements II is incorrect
- CBoth Statements I and Statements II are correct
- DStatements I is incorrect but Statements II is correct
Correct answer
B. Statements I is correct but Statements II is incorrect
Step-by-step solution
Astronomical unit denotes roughly the distance from Earth to the Sun. Parsec is a unit of length used to measure the large distances to astronomical objects outside the Solar System. A light-year is another large unit of length used to express astronomical distances.
The relation between these units are as follows:
Thus, .
Hence, Statements I is true but Statements II is false.
