Answer:

The correct option is B. 252

Step-by-step explanation:

Total number of peoples in the group = 10

Number of peoples needed to be selected from the group of 10 peoples = 5

We need to find the total number of ways in which we can select the 5 peoples.

\text{So, Number of ways of selecting the 5 people out of 10 = }_5^7 \txterm{C}

\text{So, Number of ways of selecting the 5 people out of 10 = }\frac{10!}{5!\times 5!}

\text{So, Number of ways of selecting the 5 people out of 10 = }252

Hence, Total number of required ways = 252

Therefore, The correct option is B. 252
