Answer:In flask B, the boiled seeds initially performed respiration in which they use little amount of oxygen. But it did not last long and hence, the rise in water level is less. Boiled seeds (flask B) are used as a control in the experiment of respiration to show that oxygen is necessary during respiration.

Explanation:
In the experiment proving oxygen is used up in respiration we see that there is a slight increase in the level of water in the delivery Tube of flask B, this is because in flask B there is soda lime present which absorbs the little amount of Co2 present inside the flask b from this a pressure is created in class B which results the water to slightly increase in the delivery tube.
