A.
Number of days the user is warned before the expiration date = 7
B.
Minimum number of days required between password changes = 0
C.
Maximum number of days the password is valid = 99999
D.
Last password changed = 13064 days since 1970, Jan 1th
C, not B. Max number of days before password must be changed (not Min), so C is the best answer.
