Sarah has a certain amount of money budgeted for tea and snacks during the work week, and she always aims to spend her entire budget. If she spends her entire budget on tea, she can afford 40 cups of tea. If she spends her entire budget on snacks, she can afford 8 snacks. What is the opportunity cost of a snack

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.
