None of the above

Detailed explanation-1: -An array is a series of memory locations – or ‘boxes’ – each of which holds a single item of data, but with each box sharing the same name. All data in an array must be of the same data type . This would work, but there is a better way. It is much simpler to keep all the related data under one name.
Detailed explanation-2: -An array is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. Depending on the language, array types may overlap (or be identified with) other data types that describe aggregates of values, such as lists and strings.
Detailed explanation-3: -An array is a consecutive group of memory locations that all have the same name and the same type. To refer to a particular location, we specify the name and then the positive index into the array. The index is specified by square brackets, [].
Detailed explanation-4: -An array is defined as the collection of similar types of data items stored at contiguous memory locations. Arrays are the derived data type in C programming language which can store the primitive type of data such as int, char, double, float, etc.
Detailed explanation-5: -A memory array is a linear data structure that stores a collection of similar data types at contiguous locations in a computer’s memory. Memory arrays are categorized as one-dimensional arrays and multiple-dimensional arrays. Arrays are among the oldest data structures and are used in almost every computer program.
