Look at the department store plan in B. Which floor will you go to if you want to boy:​

To determine which floor to go to if you want to buy something, we need to analyze the department store plan shown in image B.

Looking at the image, we can see that there are four floors in the department store: Lower Basement, Upper Basement, Ground Floor, and First Floor. Each floor has different sections for various products.

To find the floor where you can buy something, we need to consider the symbols and labels on the plan.

First, let's look for the symbol or label indicating where the products for boys are located. In this case, we can see the label "Boy's wear" on the First Floor. This tells us that the section for purchasing items specifically for boys is on the First Floor.

Therefore, if you want to buy something for boys, you should go to the First Floor of the department store.

It's important to note that if the department store plan had different symbols or labels, we would need to analyze them accordingly. Always pay attention to the provided information in the plan to determine the correct floor for your desired purchase.
