Option 1 suggests that stomata are involved in the absorption of water, xylem is involved in aspiration, root hairs are involved in the transport of food, and phloem is involved in the transport of water. This does not align with the correct matching of structures and functions.

Option 2 correctly matches stomata with aspiration, xylem with the transport of water, root hairs with the absorption of water, and phloem with the transport of food. This is the correct answer.

Option 3 suggests that stomata are involved in the absorption of water, xylem is involved in aspiration, root hairs are involved in the transport of water, and phloem is involved in the transport of food. This does not align with the correct matching of structures and functions.

Option 4 suggests that stomata are involved in the absorption of water, xylem is involved in the transport of food, root hairs are involved in aspiration, and phloem is involved in the transport of water. This does not align with the correct matching of structures and functions.

Therefore, option 2 is the correct answer as it accurately matches the structures given in column A with the functions given in column B.
