I don't know the actual solution to this, but looking at the options, only one of them when cubed will end with 5 (option 3). all the others cubed will lead to numbers ending with 3,6 or 4.

Not a very algebraic solution but whatever works ig

Wild, no clue what they're testing lol, Still believe option 3 is the intended answer (despite innacuracy) because it ends with 5.

probably meant to be an easy question to bamboozle people?
