• A. Earthworm floats along with flooded water
• B. Earthworm breathes in the oxygen from the porous soil with the help of it's moist skin
• C. Soil pores are filled with water when it rains
• D. Both B and C

Answer 1

The correct option is D Both B and C

All the terrestrial animals breathe oxygen from the air with our lungs. An earthworm breathes oxygen by absorbing it through its moist skin. It likes damp soil, but if the rain is very heavy, the oxygen in the water-logged soil may run out.

So the correct option is ' Both B & C ' .
