The correct answer is A. Specializing
Explanation:
In agriculture specializing means only one product or crop is grown in an area, this means no other products that the one has been chosen to grow are available in that specific area which is called crop specialization, also, this usually implies the same product or crop will be grown for a long time, replacing old plants for new ones of the same kind if necessary. Specializing crops do not allow a diversity of products, but generally, the quality of the product being grown is higher in comparison with products grow in the same area as others. Considering Tom has decided to grow only one product (potatoes) even when it is possible to grow more than one, the type of farming he is doing is specializing, as only one product will be grown in Tom's area and he will probably continue growing potatoes for a long time.
