The true statement is: "Tadpoles breathe through gills".

Here's why:

1. Tadpoles, which are the larval stage of amphibians like frogs and toads, do indeed breathe through gills. They live in water and use their gills to extract oxygen from the water, much like fish do.

2. The statement "The tracheae and spiracles pass the gases to the lungs in insects" is incorrect. Insects do have tracheae and spiracles, but they don't have lungs. Instead, the tracheae deliver oxygen directly to the insect's tissues.

3. The statement "Fish breathe through diffusion through moist skin" is also incorrect. While some oxygen can be absorbed through a fish's skin, the primary method of oxygen absorption in fish is through their gills.

4. The statement "The earthworm breathes through skin and tracheae" is partially correct and partially incorrect. Earthworms do breathe through their skin, but they don't have tracheae. Instead, oxygen passes through their moist skin directly into their bloodstream.
