From the opposite graph, we can conclude
that .
@the transpiration rate is constant along the day.
(b) the highest flow of water in the stem is less than the high transpiration rate.
© there is no relationship between the water
flow in stem and the transpiration rate.
(d) the transpiration rate can't reach zero

From the opposite graph, we can conclude  that the highest flow of water in the stem is less than the high transpiration rate.

Explanation:

From the graph shown, it is crystal clear that the highest flow of water in the stem is less than the high transpiration rate.
