The correct answer is B. Pteridophytes.
Pteridophytes are a group of plants that have vascular tissue, but do not have seeds. They reproduce through spores, which are tiny, dust-like reproductive units. Pteridophytes have the largest number of chromosomes of any plant group, with some species having up to 1,200 chromosomes.
Human beings have 46 chromosomes, elephants have 56 chromosomes, and bryophytes have 16 chromosomes.
Pteridophytes are a diverse group of plants that includes ferns, horsetails, and club mosses. They are found in a variety of habitats, including forests, wetlands, and deserts. Pteridophytes play an important role in the environment by providing food and shelter for animals, and by helping to regulate the climate.
Pteridophytes are a fascinating group of plants that have a long and complex history. They are the first plants to have evolved vascular tissue, which allowed them to grow larger and taller than other plants. Pteridophytes also played an important role in the development of the first land animals.
Pteridophytes are a valuable resource for humans. They are used in medicine, agriculture, and landscaping. Pteridophytes are also a popular subject of study for scientists.
