Answer 1

Answer:

Option 2: 100

Explanation:

The given code is regarding a Java array. To create an array in Java, the syntax is as follows:

type [] arrayname = new type[size]

In Java, this is possible to set a size for an array by giving an integer within the bracket. For example, int [] num = new int[100] will set the array size 100 for num . This means the num  can hold 100 components within the array.

Once the size is set for an array, the size cannot be changed in later stage.
