Frogs have lungs for breathing, but they also absorb dissolved oxygen directly through their skin. This allows respiration to occur when they are underwater. When they are on land, mucus keeps their skin moist to continue to absorb dissolved oxygen from the air. Which statement about water is best illustrated by this example? Liquid water can transport nutrients. Water breaks down into oxygen molecules for respiration. Water is found in every cell of an animal’s body. Liquid water is necessary for plants and animals.

I believe the best answer would be the second choice. Water breaks down into oxygen molecules for respiration, based off the information given in the short paragraph about respiration in frogs.  Hope this helps! Have a wonderful day! :)
