The trade union’s seemingly rightful demand is only a stalking horse to blackmail the management. A. trick B. proposal C. pretence D. suggestion

The correct answer is: A. trick

A stalking horse is a trick or ploy used to deceive someone. In this case, the trade union is using its seemingly rightful demand as a way to blackmail the management.

The other options are incorrect because:

• A proposal is a formal offer to do something.
• A pretence is a false appearance or show.
• A suggestion is a proposal or recommendation.
