Explanation

Bryophytes — Riccia and Marchantia (liverworts) and Funaria (a moss) — are called the “amphibians of the plant kingdom” because, though they grow on land, they need water for sexual reproduction (their motile sperms swim to the egg). Spirogyra is a filamentous green alga (Chlorophyta), fully aquatic and not a bryophyte. Hence (A) Spirogyra cannot be so called.
