The correct option is C Funaria
Green protonemal filaments may arise from the unspecialized cells of the various parts of the sporagonium. These protonemal filaments bear lateral buds, each of which develops into a leafy gametophore. The production of leafy gametophytes directly from the vegetative cells of the sporogonium without the intervention of spores is called as apospory. The aposporously produced gametophores are normal in appearance, but genetically they are diploid. In Funaria the main plant body is free-living gametophyte (n) which exist in two forms i.e., protonema (juvenile gametophyte) and leafy gametophore (adult gametophyte).
