Explanation:

Specialization refers to a situation where an individual or group of individuals concentrate on a particular aspect or field. Workers can focus on those aspects of the production process where they have the necessary skills.

Therefore options A and B are correct.

Option C is incorrect since workers will focus on a particular task. Option D is a disadvantage of specialization and is therefore incorrect.
