Final answer:
Option (A), Margaret Kemble Gage likely worried about her husband's loyalty to the British Crown and the well-being of her family during the American Revolutionary period amidst significant social upheaval.
Step-by-step explanation:
Margaret Kemble Gage's primary concern during the American Revolutionary period revolved around her personal circumstances, being the wife of a British general during a time of upheaval and conflict. Given the tensions of the American Revolution and the divided loyalties within the colonies, she likely worried about her husband's loyalty to the British Crown.
As women often did at the time, she might have also been concerned with the well-being of her family and the uncertainties that came with war, including the fate of her husband, Thomas Gage, who was a key figure in the early days of the conflict. The American Revolution caused significant social upheaval, and many women, regardless of their stance as Patriots or Loyalists, endured hardships such as loneliness, anxiety, and increased responsibilities at home while their male relatives went off to fight.
