Answer:
The correct answer to this question is option (a).
Explanation:
In the programming language (java) the syntax for declaring,initializing single denominational array can be given as:
Syntax:
datatype array[] arrayname; // declare the array
Example: int [] a;
a = new int[5]; // create the array
int [] n ={2,5,7,9,3}; // initialize all elements
Or
a[0] = 2;
a[1] = 22;
a[2] = 12;
a[3] = 20;
a[4] = 23;
In the above we define the way to initialize the array. So the correct way to set array element is option (a).
