The correct answer is Option (3) → Research and Development
Tertiary activities provide services. Trade, transport and communication are tertiary services. Quaternary activities are an advanced form of services based on research, development and specialised knowledge.
Option (1) Transport activities — A tertiary activity. Transport is a tertiary service used to overcome distance.
Option (2) Communications — A tertiary activity. Communication is a tertiary service.
Option (3) Research and Development — Not a tertiary activity. Research and development is a quaternary activity, so it is the odd one out.
Option (4) Trade and Commerce — A tertiary activity. Trade is a tertiary service of exchange.
NCERT (2026-27): “Tertiary activities include both production and exchange. The production involves the ‘provision’ of services that are ‘consumed’. The output is indirectly measured in terms of wages and salaries. Exchange, involves trade, transport and communication facilities that are used to overcome distance.” “Quaternary activities involve some of the following: the collection, production and dissemination of information or even the production of information. Quaternary activities centre around research, development and may be seen as an advanced form of services involving specialised knowledge and technical skills.” |
