b. cellulose in cell walls

c. sexual reproduction

d. alternation of multicellular generations

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.
