Step-by-step explanation:

Answer 2

Answer:

(Option B

(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

$2a+1$

Let the second odd number be

$2B+1$

By adding the two numbers, we will have

$2a+1+2B+1=2(a+B)+2$

Hence,

The sum of two odd numbers is even

Step 2:

The difference of two odd number

Let the first odd number be

$2a+1$

Let the second odd number be

$2B+1$

To find their difference, we will have

$2a+1-(2B+1)=2a+1-2B-1$

$=2a-2B$

Hence,

The difference between two odd numbers is even

Step 3:

Let the first even number be

$2a$

Let the second odd number be

$2B+1$

By adding the two numbers, we will have

$2a+2B+1$

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

$2a$

Let the second odd number be

$2B+1$

Hence,

The difference will be

$2a-(2B+1)$

$2a-2B-1$

Hence,

The difference between an odd number and an even number is odd

Therefore,

The correct answers are OPTION B and OPTION C
