• A. sweat glands
• B. lungs
• C. rectum
• D. uriniferous tubules

Answer 1

The correct option is D uriniferous tubules

The contractile vacuole helps in maintaining the osmotic concentration of the cell by controlling the amount of water in the cell. The uriniferous tubules of the kidney also play a similar role in osmoregulation. Hence we say that the contractile vacuole is analogous to the uriniferous tubules.
