Answer:
D) Beryllium and Magnesium
Explanation:
All elements in the periodic table that are "grouped" into vertical columns have similar properties, and are called a "family"
Lithium and Beryllium are both metals but one is alkaline earth metal and the other is just an alkali metal, and they're not in the same group
Lithium and Magnesium are the same thing as said above, they're not in the same group
Same with Beryllium and Sodium
Beryllium and Magnesium are both in the same group so they would have the properties most similar to each other
