The correct options are
A
Sieve tubes

B
Companion cells

D
Phloem fibres

Phloem is the food-conducting tissue of plants. It is a complex permanent tissue composed of different types of cells- sieve tubes, phloem fibres, companion cells and phloem parenchyma.
Sieve cells are elongated cells with minute pores. They help in the transportation of food prepared in the leaves to other parts of the plant.

Phloem fibres provide mechanical strength to the plant.

Phloem parenchyma cells are involved in the storage of reserve substances and certain specialized parenchyma cells, closely associated with sieve cells, are known as companion cells.
