Outsourcing
(a) restricts only to the contracting out of Information Technology.
(b) restricts only to the contracting out of non-core business.
(c) includes contracting out of manufacturing and R&D 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).
