Si dues empreses mantenen el mateix estoc de seguretat i una té un termini de proveïment de quinze dies i l'altra de sis dies, quina de les dues presenta un punt de comanda més alt? Per què?

Explanation:

Here's a clearer rendering of the question:

"If two companies maintain the same security stock and one has a supply period of fifteen days and the other six days, which of the two has a higher order point? Because?"

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.
