Giving brainlyist to the first person who gets a complete and correct answer.
Andreas93 [3]

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
