Gary, a new salesperson for a reputed cellphone manufacturer, meets the owner of a transport company that employs 50,000 people as cab drivers. On his first meeting, he plans to sell mobile phones to all the 50,000 cab drivers because he believes his firm's mobile phones are the best in the market. Which of the following is a drawback of this primary call objective?

a. It is too qualitative.
b. It is unrealistic.
c. It is irrelevant.
d. It is less optimistic.
e. It cannot be measured.

Option B. It is unrealistic

Explanation:

The reason is that the people have different likes which means we will never see 100 percent acceptance from the customers which might in the way of rejecting the offer of Gary. So the assumption that 50,000 cab drivers will purchase its product is truly optimistic which in other words is unrealistic assumption. So the option B is correct.

Option A is incorrect because the assumption is less qualitative as it doesn't relies on realistic assumption.

The cab drivers sales are relevant here but the sales assumption was unrealistic (Highly optimistic assumption) so the option C and D are incorrect.

Option E is also incorrect because the sales to cab drivers can be measure by initially directly selling 1000 cell phone to 1000 cab drivers which will give an actual idea of sales units expected, which means it is measurable.

its simple as this, microeconomics is the study of economics at an individual, group or company level, macroeconomics on the other hand, is the study of a national economy as a whole.
