The passage below describes how the engineering-design process was used to test a solution to a problem. Read the passage. Then answer the question below.

a drone without blade guards

Gabby was designing small aircraft called drones to pick up items from warehouse shelves. She knew that the drones' propeller blades would get damaged if they bumped into anything while flying through the warehouse. So, Gabby wanted to add blade guards to protect the propeller blades. The guards had to be sturdy so they would not break in a crash. But she thought that if the guards weighed too much, the drones would not fly well.

So, Gabby put guards made of lightweight metal on one drone. Then she observed how well the drone flew with the guards.

Which of the following could Gabby's test show?

• Ahow much the drone weighed with the blade guardshow much the drone weighed with the blade guards
• Bif the blade guards would break in a crashif the blade guards would break in a crash
• Cif adding the blade guards made the drone fly poorly
