Answer:
Option (B)
Explanation:
To measure the distance between two objects we use the units of length.
To measure small distances we use, mm or cm or m. But if we measure large distances between two objects we use large units such that kilometer or miles.
To measure the very large distances between two objects we use large units such as Astronomical unit or Parsec.
The Astronomical unit is defied as the distance between earth and Sun.
Thus, the distance between earth and the sun is defined as 1 Astronomical unit.
1 Astronomical unit = 1 A.U. = 1.5 x 10^8 km = 1.5 x 10^11 m
According to Jean Piaget, unrealistic idealism often occurs in adolescence as a result of egocentrism. Egocentrism is defined as the inability to understand or comprehend any point of view other than their own. Piaget claimed that adolescents are egocentric and are only seeing the world only from their personal point of view.
