Solution
The correct option is D Perennials
Plant groups like ephemerals, annuals and biennials show clear cut demarcation between vegetative, reproductive and senescent phases of life cycle. But in perennials reproduction occurs more than once in their life span. Hence it is very difficult to define these phases.
