Answer:
Option C.
Step-by-step explanation:
The given credit scores are 575, 775, 875 and 675.
We need to find a credit score which is not valid.
300 - 579 means poor FICO credit score.
580 - 669 means fair FICO credit score.
670 - 739 means good FICO credit score.
740 - 799 means very good FICO credit score.
800 - 850 means exceptional FICO credit score.
The range of FICO credit score is 300-850. Since 875 is more than 850, therefore 875 is not a valid FICO credit score.
Thus, the correct option is C.
