MCQ

Given below are two statements :

Statements $I$ : Astronomical unit $(Au)$. Parsec $(Pc)$ and Light year $(ly)$ are units for measuring astronomical distances.

Statements $II:$ $Au < Parsec ( Pc ) < ly$

In the light of the above statements. choose the most appropriate answer from the options given below:

A
Both Statements $I$ and Statements $II$ are correct.
✓
Statements $I$ is correct but Statements $II$ is incorrect.
C
Both Statements $I$ and Statements $II$ are incorrect.
D
Statements $I$ is incorrect but statements $II$ is correct.

✓

Answer

Correct option: B.

Statements $I$ is correct but Statements $II$ is incorrect.

b
$1 AU =1.496 \times 10^{11}\,m$

$1 \text { par sec }=3.08 \times 10^{16}\,m$

$1 \text { light year }=9.46 \times 10^{15}\,m$

So, $Au < ly < Per\,sec$
