When determining whether to shut down in the short run, a competitive firm should ignore (i) fixed costs. (ii) variable costs. (iii) sunk costs. A. (ii) only B. (i) and (iii) only C. (iii) only D. (i), (ii), and (iii)

B) (i) and (iii) only

Explanation:

When a competitive firm must decide whether it shuts down or not in the short run, it must only focus on the variable costs and the marginal revenue. As long as the marginal revenue ≥ variable cost, then the firm should continue to operate in the short run, at least until the market stabilizes.

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
