The correct answer is: Movement can occur both upward and downward in the plant.
Phloem is a plant tissue (in vascular plants) that transports the organic compounds made during photosynthesis in the form of sap-water based solution rich in sugars. Phloem is composed of living cells generally called sieve elements. Transport of sap is multidirectional: sometimes sugars made in photosynthesis are transported to non-photosynthetic parts of the plant, such as the roots but sometimes roots are sugar sources so the sap needs to be transported upward for the plant’s growth.

Explanation:
I'm not sure what the multiple-choice answers are but knowing that: abiotic factors are non-living chemical and physical parts of the environment that affect living organisms.
