The question seems to be related to permutations or combinations, but without specific context, it's challenging to provide a detailed explanation. However, if we interpret this as a simple permutation problem where we want to find the number of ways to arrange n items out of N (without repetition), the formula is N! / (N-n)!. For n=2 and N=5, this calculation is 5! / (5-2)! = 5*4 = 20. However, given the choices and the correct answer indicated, it seems there might be a misunderstanding in the interpretation. If we consider a simple combination or another operation that results in 10 as the correct answer, it could be a basic calculation mistake or a misinterpretation of the question's intent. Without more context, it's challenging to provide a precise explanation.
