Arranging Order +4 −1

of a set of n elements is an arrangement of the elements in a given order:

Combination Permutation Correct Exponent Logarithm

Combinatorics - Permutation vs. Combination:
Permutation of a set of $n$ elements is an arrangement of the elements in a specific, definite order:

$$P(n, r) = \frac{n!}{(n - r)!}$$

Combination is a selection of elements where the order of arrangement does not matter:

$$C(n, r) = \frac{n!}{r!(n - r)!}$$

Conclusion: An arrangement in a given order is a Permutation (Option 2).

Correct option: (2) Permutation
