Solution

The correct option is B Development of plant occurs in sequence phases.
'Theory of phasic development' in plants : Investigations on the cause of the failure of winter plants to ear in the sowing year have led to a theory of plant development based upon a discrimination between growth and development. The latter is regarded as a sequence of qualitative changes or phases, each consisting of complex internal adjustments which lead to eventual reproduction.
