Solution
The correct option is B
Rhizophora
As a viviparous plant, Rhizophora creates a propagule that is in reality a living tree.
Though resembling an elongated seed pod, the fully-grown propagule on the
mangrove is capable of rooting and producing a new tree. The trees are hermaphrodites,
capable of self pollination or wind pollination.
The tree undergoes no dormant stage as a seed, but rather progresses to a live
plant before leaving its parent tree. A mangrove propagule may float in
brackish water for over a year before rooting. So, the correct answer
is 'Rhizophora'.
