Social megatrends (Option C) include:

Changing demographics (aging populations, urbanization).

Shifts in family structures (declining birth rates, single-parent households).

Labor market shifts (rise of gig economy, diversity in the workforce).

Option A (Mass migration) is a factor but not the primary social megatrend—it’s more of a geopolitical or economic trend.

Option B (Changes in family structures + mass migration) excludes demographics, which is a core social megatrend.
