(D) Ricca and Marchantia are liver worts

• A. A and B are true and C and D are false
• B. A and C are true and B and D are false
• C. A and D are true and B and C are false
• D. B and D are true and A and C are false
• E. B, C and D are true and A false

Answer 1

The correct option is E B, C and D are true and A false

Merosity is a term that refers to the number of component parts in each whorl of the plant basically the flowers which include, sepals, petals, and stamens. the trimerous condition is a characteristic feature of monocots and is found in Liliaceae.
Walking fern refers to the species of Asplenium. Adiantum caudatum is walking maidenhair.
The vascular system of gymnosperms is made up of xylem with tracheids, parenchyma, and rays. vessels are however present in Gnetum, Ephedra having evolved from pitted tracheids. The phloem is made up of sieve cells but companion cells are absent.
Riccia and Marchantia are liverworts a belong to the order Marchantiales. Thus, the correct answer is option E.
