Final answer:
The term e-procurement describes the electronic handling of various procurement processes, such as sourcing, ordering, and negotiating with suppliers, which enhances efficiency and can reduce costs. Thus, the option "a" is the correct answer.
Step-by-step explanation:
E-procurement is the term used to describe various procurement functions that are now done electronically. This includes activities such as the sourcing and ordering of goods and services, as well as the negotiations with suppliers that are conducted online. The choice of options provided in the question suggests a focus on procurement-related concepts, and among them, e-procurement specifically refers to the use of electronic processes to facilitate the complete purchasing process from requisition to payment, optimizing the procedures and making them more efficient, time-saving, and oftentimes more cost-effective than traditional methods. Other options, such as MRO Procurement, Strategic Procurement, and Centralized Procurement, are distinct procurement strategies or practices, but they do not imply an electronic method of carrying out procurement tasks inherently.
