Answer:
A
Explanation:
The number of different combinations is the number of different type of each items multiplied together.
To select bundles of "backpack", "binder", "pencil", & "notebook", we see how many different type of each are there and just multiply them. Hence:
"There are 5 types of backpacks, 5 types of binders, 3 types of pencils, and 2 types of notebook paper"
So, 5 * 5 * 3 * 2 = 150
The correct answer is A
