Place the following events in order to sequence the evolution of life on earth. (a)prokaryotes (b)land plants (c)multicellular eukaryotes (d)single-celled eukaryotes (e)formation of earth

a, e, d, c, b
e, a, d, c, b
b, c, d, a, e
e, d, c, a, b

The correct sequence would be E, A, D, C, B

Explanation:

For the evolution of life to begin, the Earth formed as Earth is the only planet which can support life and has favourable conditions. Life first began from prokaryotic organisms which engulfed smaller prokaryotes and gave rise to unicellular eukaryotes. With the passage of time, the unicellular eukaryotes evolved to form multicellular eukaryotes. The life on Earth then started after the formation of multicellular eukaryotes in the oceans and seas.
