- BThey have a strong tolerance to extreme temperatures.
- CThey can live both on land and in water.

Show answer and explanation
Correct answer: (d) They require water for sexual reproduction.
Explanation
Bryophytes (mosses and liverworts) are called the amphibians of the plant kingdom because they live on land but depend on water for sexual reproduction. Their male gametes (antherozoids) must swim through a film of water to reach the egg in the archegonium.
So, like amphibian animals, they live on land but still need water to complete their life cycle. They usually grow in damp, shady places.
