Which of the following are known as amphibians of plants?

Bryophytes (mosses and liverworts) are called 'amphibians of the plant kingdom' because they need water for sexual reproduction, similar to how amphibians need water for breeding. They live on land but require water for fertilization. Pteridophytes (A) are ferns, while 'metaphytes' (C) and 'thallophytes' (D) are not standard classifications.
