Out of the following, which option should provide the largest rise in the value of ‘t’ ?
(A) Instead of 4-decimal-digits, maintain the personal secret code in 4-hexadecimal-digits.
(B) Instead of 4-decimal digits, maintain a 5-decimal-digit personal secret code.
(C) Reduce the processing speed of the ATM terminals to the half of their current speed.
(D) None of the above provides any improvement.
