The Correct Option is B
Solution and Explanation
The number of diagonals in a $n$ -side polygon
$=\frac{n(n-3)}{2}$
$\therefore$ Number of diagonals in a hexagon
$=\frac{6(6-3)}{2} $
$=9$
$=\frac{n(n-3)}{2}$
$\therefore$ Number of diagonals in a hexagon
$=\frac{6(6-3)}{2} $
$=9$

Concepts Used:
Combinations
The method of forming subsets by selecting data from a larger set in a way that the selection order does not matter is called the combination.
- It means the combination of about ‘n’ things taken ‘k’ at a time without any repetition.
- The combination is used for a group of data where the order of data does not matter.
- For example, Imagine you go to a restaurant and order some soup.
- Five toppings can complement the soup, namely:
- croutons,
- orange zest,
- grated cheese,
- chopped herbs,
- fried noodles.
But you are only allowed to pick three.
- There can be several ways in which you can enhance your soup with savory.
- The selection of three toppings (subset) from the five toppings (larger set) is called a combination.
