To channelise the activities of the workers and to induce them to work is

control
coordination
motivation
organisation

The correct answer is C. motivation.

Motivation is the driving force that causes people to act. It is what makes people get up in the morning and go to work, and it is what keeps them going even when things are tough. Motivation can come from a variety of sources, including internal factors such as personal goals and values, and external factors such as rewards and punishments.

In the context of the question, motivation is important because it is what will drive the workers to channel their activities in the right direction and to work hard to achieve their goals. Without motivation, the workers would be more likely to slack off and not put in the effort required to succeed.

The other options are not as relevant to the question. Control is about ensuring that people are following the rules and regulations, coordination is about ensuring that different parts of an organization are working together effectively, and organization is about creating a structure and system for getting things done. While all of these things are important, they are not as directly related to motivating people to work hard as motivation is.

In conclusion, the correct answer to the question “To channelise the activities of the workers and to induce them to work is” is C. motivation.
