Hi.

a) is the answer

thanks

I didn't know alfalfa was a legume until I looked on the Internet.

To determine which of the given options are legumes, we need to understand what legumes are. Legumes are a type of plant that belong to the family Fabaceae and are known for their seeds or fruits that grow in pods. They are a rich source of protein, fiber, and other nutrients.

Now, let's go through each option and identify the legumes:

a) Peas, beans, and alfalfa: Peas and beans are well-known legumes, as they have seeds that grow in pods. Alfalfa is also a legume and is commonly used as livestock feed. Therefore, option a contains legumes.

b) Carrots, potatoes, and beets: Carrots, potatoes, and beets are not legumes. They belong to different plant families and do not have seeds or fruits that grow in pods. Therefore, option b does not contain legumes.

c) Peas, spinach, and rhubarb: Peas are legumes, as discussed earlier. However, spinach and rhubarb do not belong to the legume family. They are leafy green vegetables. Therefore, option c contains one legume but two non-legumes.

d) Celery, carrots, and onions: Celery, carrots, and onions are not legumes. They belong to different plant families and do not have seeds or fruits that grow in pods. Therefore, option d does not contain legumes.

Based on the above analysis, the correct answer is option a, which includes peas, beans, and alfalfa, all of which are legumes.
