Solution

The correct option is B Phenology
  • Phenology is the study of periodic plant and animal life cycle events and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation).
  • Phenology has been principally concerned with the dates of the first occurrence of biological events in their annual cycle. Examples include the date of emergence of leaves and flowers, the date of leaf colouring and fall in deciduous trees etc..
  • Hence, the timing of seasonal activity in relation to changes in environmental conditions is termed as Phenology.
So, the correct answer is 'Phenology'.
