The correct answer is d. Delays in the average age at which marriages.<br /><br />Explanation: Social trends such as delays in the average age at which marriages can lead to an increase in the number of households. As people marry later in life, they are more likely to live independently and form their own households. This trend has been observed in many societies where individuals prioritize education, career advancement, and personal growth before settling down and starting a family.
