Correct answer: A. Training supervision and compliance record
Explanation: Direct answer: Option A is correct. Here the method itself is good, but the problem is compliance: employees are not following it. Control must therefore address knowledge, behaviour and evidence. First, training explains the correct steps and the reason behind them. Second, supervision checks whether the steps are actually being followed and allows timely correction. Third, a compliance record documents what happened, who checked it and whether improvement occurred. Option A combines all three. Option B, a new logo, changes appearance but does not teach or monitor behaviour. Option C, painting the shop, changes the environment’s look and has no direct control value. Option D, an advertising song, communicates with customers rather than ensuring internal compliance. The aim is supportive control, not mere punishment: train, observe, record and improve. Memory cue: when good rules are ignored, use training plus supervision plus records.
