Solution

The correct option is A Passive transport
Pholem is the food-conducting tissue.
The sugar sucrose is transported from the companion cells to the sieve tube by the mechanism for simple diffusion because of the concentration gradient.
The concentration of the sucrose is higher in the companion cells an lower in sieve tubes.
So, the correct option is 'Passive transport'
