Solution

Land plants are those members of plant kingdom where the habitat is terrestrial. They are grouped into several categories based on reproductive organs and complexity of vascular structures. They are; bryophytes, mosses, ferns, lycophytes, gymnosperms and flowering plants. Red algae are found mostly found in sea and oceans. Only few are found in freshwater. Land plants originated from freshwater algae. Brown algae form a large group of marine algae that includes giant algae such as kelp (seaweed). However, they are not ancestor of land plants because they do not have photosynthetic pigments like land plants. Angiosperms are higher members of the land plants and not its ancestors.
So the correct option is 'none'.
