(ii) Sum of two odd numbers is an even number.
Let us consider two odd numbers 1 and 3.
So,
1+3=4,
The sum is 4 which is an even number.
Let us consider two odd numbers 3 and 5.
So,
3+5=8
The sum is 8 which is an even number.
Hence, the sum of two odd numbers is always an even number.
So, the statement is true.
