Astronomical Unit (AU)
1 AU = 1.50 x 10^11 m
Light year (lyr)
1 lyr = 9.46 x 10^15m
Parsec (pc)
1 pc = 3.08 x 10^16 m
From smallest to largest, the correct order of these astronomical distance units is
C) AU, light-year, parsec
The correct answer would be B. The first level contains two and the second level contains six holding a total of eight, the reason eight aren't just in one row is because only two fit in the first row.
Its 21!! sorry i was late! :)
