Correct answer: C. Policy
Explanation: Direct answer: Option C, Policy. The company is stating the principles that should guide grievance decisions: written evidence and a fair hearing should matter, not the employee's status or power. This is broad and fair decision guidance, so it is a policy. Option C is correct. Option A, Procedure, would describe the ordered steps for handling a grievance, such as receiving a complaint, investigating it, conducting a hearing and communicating the decision. The statement does not give those steps. Option B, Rule, would be a strict instruction, such as always accepting or rejecting a complaint under a specified condition; here the organisation gives principles for judgement. Option D, Method, would identify a particular technique for doing work, not a standard for impartial decisions. The policy helps reduce favouritism and makes decisions more consistent. Memory cue: principles that guide fair judgement are policy; ordered steps are procedure.
