<span>The oceanic crust is part of the crust that is made fully out of basaltic rock and is several times thinner than the continental crust which is made out of granitic rock. Oceanic crust underlies Earth's oceans and is produced at divergent plate boundaries which are commonly referred to as mid-ocean ridges. As it grows from infilling magma and spreads away from the ridges, it will becomes cooler, thicker, and more dense, and will eventually sink into the mantle.</span>
        
                    
             
        
        
        
Answer: d. alternation of multicellular generations
Explanation:
The gametophytic as well as the sporophytic generations are alternative in the life cycle of the multicellular plants. This can be seen among the land plants. This feature cannot be seen in the algal species as they are unicellular in nature. Thus cannot be seen in the relatives of charophyta algae.

There are seven main levels of classification, divided into five kingdoms. 
Animal - Animals are multicellular eukaryotes whose cells are bound together by collagen.
Plant - Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. 
Fungi - A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.
Protist - A protist is any eukaryotic organism that is not an animal, plant, or fungus.
Monera (unicellular) - Kingdom Monera belongs to the prokaryote family. These are the oldest known microorganisms on earth.
