D

Verified step by step guidance1
Understand the context: The question is asking about a group that includes both charophytes (a type of green algae) and all land plants. This requires knowledge of plant evolution and classification.
Recall that charophytes are the closest relatives of land plants. Together, they form a clade within the green plants (Viridiplantae).
Review the term 'Streptophytes': This group includes both charophytes and land plants, distinguishing them from other green algae like chlorophytes.
Eliminate incorrect options: 'Bryophytes' refers to non-vascular land plants (e.g., mosses), 'Chlorophytes' are a separate group of green algae, and 'Tracheophytes' are vascular plants, which are a subset of land plants.
Conclude that the correct answer is 'Streptophytes,' as it encompasses both charophytes and all land plants.
