Astronomical unit (Au), Parsec (Pc) and Light year (ly) are the units of distance
Light year \rightarrow distance travelled by light in one year
\mathrm{1 ly = 9.5 \times 10^{15}m}
parsec = 3.262 lightyear
Au = \mathrm{1.58 \times 10^{-5}} light year
\mathrm{Au < 1y < Parsec.}
Statement I correct and statement II incorrect.
