hello
the answer to the question is A) 125
(if you need explanation, let me know in the comments)
Step-by-step explanation:
when you'd want to make a three letter password such as:
___ × ___ × ___
you can put 5 different letters in each blank space:
_5_ × _5_ × _5_
hence the answer is:
5 × 5 × 5 = 125
