Its option D.

Hello Team,

Many businesses do not even consider a contingency plan or realize the option exists and is a sound practice. Creating a plan is most often overlooked or forgotten when times are good and business is booming. Unfortunately, it does not take much to completely turn things around. One technical mishap that crashes a server, a missed delivery or a major project that goes unpaid can turn a business upside down in a hurry.

A contingency plan is a plan devised for an outcome other than in the usual (expected) plan.

It is often used for risk management for an exceptional risk that, though unlikely, would have catastrophic consequences. Contingency plans are often devised by governments or businesses. For example, suppose many employees of a company are traveling together on an aircraft which crashes, killing all aboard. The company could be severely strained or even ruined by such a loss.

Contingency reserves are also called time reserve, buffer or management reserve. The contingency reserves are for the identified schedule risk remaining after the risk response process. These reserves are normally included in schedule baselines. The contingency reserves are the additional fund kept aside in order to utilize at the time of occurance of unforseen risk that would impact the project.

A planned response that defines the steps to be taken if an identified risk event should occur.
