(a) Restricts only to the contracting out of Information Technology Enabled Services (ITES)
(b) Restricts only to the contracting out of non-core business processes
(c) Includes contracting out of manufacturing and R&D as well as service processes-both core and non-core-but restricts only to domestic territory
(d) Includes off-shoring
Outsourcing refers to the process of contracting out non-core activities of a company to external agencies. It involves outsourcing those activities which are not so essential and which are less important for a company. Thus, option (b) is correct, as it states that outsourcing is restricted only to contracting out non-core (less important) business activities.
Hence, the correct answer is option (b).
