Answer:
this isnt a multiple choice question,the other person is wrong. i also dont do math so i cant answer the actual question at the bottom, but i can translate it for u.
Step-by-step explanation:
the first number of the code (from the left) is divisible by 1.
the second number of the code (from the left) is divisible by 2.
the third number of the code (from the left) is divisible by 3.
the fourth number of the code (from the left) is divisible by 4.
etc....
the final point says:
the whole code is divisible by 10.
and the actual question states:
that is the code if you may only use each digit once?
hope this helps :)
