Answer:
 d. $33,641.50 
Step-by-step explanation:
In this question, we use the PMT formula which is shown in the spreadsheet. 
The NPER represents the time period. 
Given that, 
Present value = $375,000
Future value = $0
Rate of interest = 7.5%
NPER = 25 years
The formula is shown below: 
= -PMT(Rate;NPER;PV;FV;type) 
So, after solving this, the answer would be $33,641.50
