what is your question ??
I think u have missed some parts here in the question ..
Answer: Option (A) is correct.
Explanation:
In a competitive market, when the demand curve i.e. the marginal benefit curve is exactly equal to the supply curve i.e. marginal cost curve and at this point the sum of consumer and producer surplus is maximized then an equilibrium is set in an economy and economic efficiency is obtained.
Inefficiency occurs at a point where there is a disequilibrium in an economy which means that competitive equilibrium is not achieved by the economy.
Answer: A clear statement of the problem
Explanation:
The opening of a direct claim message should clearly state the problem that you would like to be addressed by the receiver and would set the tone for the rest of the message.
Claim messages are formal messages and as such, should be clear and concise so that the message is communicated effectively and there is a lesser chance of the message being misread. This is why the message should be clearly stated, so that the receiver understands it and responds in kind.
