Quinary industry refers to:

Quinary industry refers to:

• A. Services that used to be performed in the home
• B. Services that occur in factories
• C. Information processing services
• D. Agricultural production

Answer: (A)

The quinary sector covers services tied to households and personal life—tasks that have traditionally been done in the home, like housekeeping, cooking, child care, and elder care, often now provided professionally. This description fits best because it distinguishes these domestic or home-based services from manufacturing (secondary sector), information processing (quaternary sector), or farming and farming-related activities (primary sector). So recognizing that the quinary sector encompasses those home-oriented services explains why this option is the most accurate.
