Explanation:

Unlike the supply and demand factors related to economic growth,the efficiency factor mainly construes the expansion or improvement of the productive capacities of the factors/inputs and resources of production in the economy.Now,it does not imply the expansion of the overall production level or the quantity and quality of the existing factor inputs or productive resources in the economy.It rather emphasizes on increasing the productive and efficiency value or level of the resource endowments in the production process.Hence,the improvement of the productivity and efficiency of the factors/inputs of production and endowments entails improvement of the productive potentials and consequently leads to optimum production level that can be achieved by ensuring the least possible production costs or expenses and the increased productive capacities and efficiency level of the factor inputs and resource endowments in the economy used in the production.

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.
