Answer:
The correct answer is - a. (i) and (ii).
Step-by-step explanation:
If the market condition is favorable and Dan decides to expand his business, he will need to hire more bakers to provide more products to the market, and thus increase his profits.
If the price of muffins increases (i) it means that there is a high demand on muffins among customers, for example during Holiday season, or because another big business ceased its operation.
Similarly, in the case (ii) when Dan adds three more ovens to help his bakers to work faster, he seeks to satisfy increased demand for muffins. This is likely to lead to the expansion of his business and the need to hire more bakers.
