98,706,816 (D)

Step-by-step explanation:

Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Number of letters they can use = 4

Number they can use = 3

Total number of letters we have = 26

Total number from 0 to 5 = 6

So, Number of different key codes is given by

Hence, there are 98,706,816 different key codes.

Thus, Option 'D' is correct.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
