Explanation
Bamboo is a type of grass. It belongs to the family Poaceae, which is also known as the grass family. Bamboo is one of the fastest-growing plants in the world and is known for its tall, woody stems that can reach heights of up to 30 meters.
Unlike trees, which have a single trunk and a network of branches, bamboo has a series of jointed stems, or culms, that emerge from an underground rhizome. The leaves of bamboo are long and narrow, and they grow in a variety of patterns depending on the species.
Bamboo is widely used for a variety of purposes, such as construction, furniture, paper, and textiles. It is also an important food source for many animals, including pandas, and is used as a decorative plant in many gardens and landscapes.
Therefore, the answer is B: Grass.
