Question Options:
A) changes in religion
B) the aging of the population
C) declining birth rates
D) increasing inflation
Answer: THE AGING OF POPULATION.
Explanation: The aging of population is the correct answer in this question because what we are looking at is 'the next few decades'. The 'the next few decades' will be a minimum of twenty years. By then, the major consumers of the product will be 'an aged population'.
Changes of religion, declining birth rates , increasing inflation are not factors to be considered because they barely affect consumer preferences.
