A computer system uses alphanumeric case sensitive characters for its passwords. When the system was created it required users to create passwords having 4 characters in length. This year, it added the option of creating passwords having 5 characters in length. Which of the following gives the expression for the total number of passwords the new computer system can accept?

Assume there are 62 unique alphanumeric case sensitive characters.

(A) 63^4
(B) 62^5
(C) 62(62^4)
(D) 63(62^4)
(E) 63(62^6)

Has case sensitiveness any role to play in this question. Per this each option character has two choice higher case or lower case. Please help me out.

10 digits (0,1,2,3,4,5,6,7,8,9)
