Which of the following does NOT belong to quaternary activities?

The correct answer is Option (3) → Insurance Agents

Quaternary activities are knowledge-based services. They involve collecting, producing and spreading information and need specialised knowledge and technical skills.

Option (1) Software Developers — A quaternary activity. They produce information-based services with special technical skills.

Option (2) Mutual Fund Managers — A quaternary activity. They study markets and use expert knowledge to manage people’s money.

Option (3) Insurance Agents — Not a quaternary activity. They sell insurance policies to customers. This is an ordinary service of selling, not a knowledge-based service.

Option (4) Tax Consultants — A quaternary activity. They give expert advice based on their knowledge of tax laws.

Note: The given answer is as per the official NTA Answer Key. The book does not place insurance agents in any group of activities. It gives mutual fund managers, tax consultants and software developers as examples of information-based services of the quaternary sector, so insurance agents are the odd one out.
