A programmer is constructing an algorithm that predicts personality traits based on users' selection of their favorite ice cream flavors. Which of the following programming concepts should be used to

Vectors are dynamic arrays that can resize, offering similar functionality to arrays but with more overhead, making arrays a more fundamental choice for a simple collection.

An array is a data structure used to store a fixed-size collection of elements of the same data type. It is ideal for representing a list of ice cream flavors, where each flavor can be an individual element.

A variable stores a single piece of data, not a collection; representing multiple flavors with individual variables would be inefficient and impractical.

A constant is a fixed value that cannot change, whereas a collection of flavors is a list of distinct items, better suited for a data structure like an array.
