Parsec is the unit of measurement of (A) Mass (B) Time (C) Current (D) Distance
In physics, Parsec is a unit of distance and it is defined as when the radius of our planet earth makes an angle of a second of an arc, then the distance at which this angle subtended by earth is referred as a parsec. Mathematically 1Parsec=3.26Light years. Hence, (D) Distance parsec is a unit of measurement of Distance.
