The walking fern is so named because (a) it propagates vegetatively by its leaf tips (b) it knows how to walk by itself (c) its spores are able to walk (d) it is dispersed through the agency of walking animals.
Option A Walking fern is named so because when its leaf tips come in contact with soil, form new plants as adventitious buds develop at leaf tips. This helps in the spread of fern over a large soil surface and thus the name ‘walking fern’.
