John took a 30-year mortgage of $1 million five years ago. The mortgage requires monthly fixed equal payment with 6% interest rate. This year, John heard that his friend just took a new mortgage loan with only 4.5% interest rate from another bank. After knowing this, John decides to refinance his old mortgage. This means, he is going to make a lump sum payment to fully pay back the remaining balance of his old mortgage, and this lump sum payment is financed by a new, 25-year mortgage with fixed equal payment but only 4.5% interest rate. How much does John pay each month for the new mortgage?

A. $5,995.51

B. $5,902.28

C. $5,172.26

D. $5,066.85
