If a cellular toxin caused structure D to dysfunctional, the cell would be unable to store food, water, and waste. Thus, the correct option is B.
The structure D in the given diagram represents a membrane-bound cell organelle known as vacuoles in the plant cell.
And if suppose any cellular toxin caused this vacuole to be dysfunctional, it implies that all the functions performed by vacuoles are not completed.
The primary function of the vacuole is to store minerals, nutrients, food, water, etc. for the survival of the cell. Apart from this, vacuoles also play an important role in the storage of waste products in order to prevent the cell from being contaminated.
Therefore, if a cellular toxin caused structure D to dysfunctional, the cell would be unable to store food, water, and waste. Thus, the correct option is B.
