One reason why adjustable-rate mortgages (ARMs) have become popular has to do with the impact that they have on the interest rate risk that is borne by the parties involved. If interest rates were to rise on a level-payment mortgage (LPM) the interest rate risk of the loanwould typically be borne by:

A. the borrower only
B. the lender only
C. both the borrower and lender
D. neither the borrower nor the lender

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.
