Explanation:

To solve this question, you need to add together all the odd numbers between 20 and 32. First, identify the odd numbers within this range:

21, 23, 25, 27, 29, and 31

Now, simply add these numbers together:

$$21 + 23 + 25 + 27 + 29 + 31$$

When you perform the addition, you get:

$$156$$

So, the sum of the odd numbers between 20 and 32 is 156, which corresponds to Option B.

Remember that odd numbers are integers that cannot be divided evenly by 2. They always have a remainder of 1 when divided by 2. In contrast, even numbers can be divided evenly by 2 and have a remainder of 0. Knowing the difference between odd and even numbers is a fundamental concept in mathematics and can be useful in various problems and calculations.
