Phloem carries-
A
Glucose all around the plant
B
Glucose to the roots only
C
Water all around the plant
D
Water up from the roots
Explanation: 

Detailed explanation-1: -In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate ), particularly sucrose; a sugar, to all parts of the plant.

Detailed explanation-2: -Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar.

Detailed explanation-3: -Phloem is the primary vascular tissue that carries glucose throughout the plant.

Detailed explanation-4: -Plants have two transport systems-xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.

Detailed explanation-5: -Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients.
