As per Indian Patents Act, 1970, criteria of Patentability in India are

Novelty
Inventive step
Capable of industrial application
All of these

The correct answer is (d). All of these.

The Indian Patents Act, 1970, states that an invention is patentable if it is new, involves an inventive step and is capable of industrial application.

Novelty means that the invention has not been published in India or in any other country before the date of filing of the patent application.

Inventive step means that the invention is not obvious to a person skilled in the art.

Capable of industrial application means that the invention can be made or used in any kind of industry.

If an invention satisfies all three criteria, it is patentable in India.
