(Option C
Step-by-step explanation:
Concept:
We will start by explaining each option one after the other
Step 1:
The sum of two odd numbers
Let the first odd number be
Let the second odd number be
By adding the two numbers, we will have
Hence,
The sum of two odd numbers is even
Step 2:
The difference of two odd number
Let the first odd number be
Let the second odd number be
To find their difference, we will have
Hence,
The difference between two odd numbers is even
Step 3:
Let the first even number be
Let the second odd number be
By adding the two numbers, we will have
Hence,
The sum of an odd number and an even number is odd
Step 4:
The difference between an odd number and an even number
Let the first even number be
Let the second odd number be
Hence,
The difference will be
Hence,
The difference between an odd number and an even number is odd
Therefore,
The correct answers are OPTION B and OPTION C
