Correct Answer - Option 2 : distance

Explanation:

Parsec (parallactic second):

  • It is the largest practical unit of distance used in astronomy.
  • It is defined as the distance at which an arc of the length of 1 astronomical unit subtends an angle of 1 second of arc.

1 parsec = 3.08 × 1016 m

So clearly, it is the unit of distance. 

  • Another unit of distances are light year, Angstrom. 
  • SI unit of distance or lengrh is meter. 

  • SI unit of time is second. 
  • SI unit of frequency is hertz. 
  • SI unit of angular acceleration is sec - 2
