"Alice and Marge are studying the properties of matter. The girls cut some silver-colored magnesium sheets into 3-inch long strips and then put one strip each into test tubes: one containing water and one containing acid. Nothing happened when they added the magnesium to the water. In the acid, bubbles formed and the test tube felt much warmer."

Question

Based on the girls' experiment, what is a chemical property of magnesium?
A) Magnesium is a metal.
B) Magnesium reacts in acids.
C) Magnesium is solid at room temperature.
D) Magnesium is malleable and can be shaped into strips.

I'm assuming the answer for this is "B." I'm very confused at the moment.
