Answer

Answer:

C. strontium, calcium, magnesium

Explanation:

Step1: Recall periodic - table trends

In the periodic table, for Group 2 elements (alkaline - earth metals), reactivity increases down the group.

Step2: Locate elements

Calcium (Ca), magnesium (Mg), and strontium (Sr) are Group 2 elements. Strontium is in period 5, calcium in period 4, and magnesium in period 3.

Step3: Determine reactivity order

Since reactivity increases down the group, strontium is the most reactive, followed by calcium, and then magnesium.
