In an array declaration, “size declarator” indicates the number of elements that the array will have.
Hence, the correct answer is option “B”.

Explanation of Solution
Size declarator:
In an array the “size declarator” must be a non-negative integer expression. It may be a variable or a literal value. It is a common practice to use a final variable as a size declarator.
Example:
final int NUM_ELEMENTS = 6;
int[] numbers = new int[NUM_ELEMENTS];
Explanation for wrong answers:
a.Subscript:
A “subscript” is used as an index to pinpoint a specific element within an array.
Hence, the option “A” is wrong.
c.element sum:
The “element sum” is used to add the numbers of element in an array.
Hence, the option “C” is wrong.
d.Reference variable:
The user declare a “reference variable” and use the new keyword to create an instance of the array in memory. The reference variable can be declared as follows:
numbers = new int[6];
Hence, the option “D” is wrong.
