I will use 0b to refer to binary numbers: ex: 0b1 = 1, 0b10 = 2
0b100 = 4 and 0b11 = 3
4+3 = 7
convert 7 to binary and you get 111.
Hope this helps, and May the Force Be With You!

4. Only (ii)
<u>Explanation:</u>
The declaration of the array can be of two types:
1. int a[100];
2. int[] a = new int[100];
The general thing about an array is that whenever we want to undergo traversal in an array, we always have to start from the 0th position as the size of the array may be a whole number (let us say 10). So, to undergo traversal in an array, we start from 0 to n-1 (in this case 9) such that it covers the size of the array. 
The size of an array can be finite or infinite. The general rule is it starts from 0 to n-1 where n is the size of the array. In the above example, the range of the index of the array will be 0 through 100 and not 1 through 100.
