Which one of the following options is the definition of an interested party in an...

The correct answer is D . ISO 14001:2015 defines an interested party in Clause 3.1.6 as a “person or organization that can affect, be affected by, or perceive itself to be affected by a decision or activity.” This directly matches option D .

Option B is close but incorrect because it uses “influence / be influenced by” , while the ISO definition uses “affect / be affected by.” In ISO 14001, interested parties may include regulators, customers, employees, contractors, neighbours, suppliers, local communities, or NGOs, depending on the EMS context.
