Answer: Option (D) is the correct answer.
Explanation:
It is known that elements which belong to same group show similar chemical properties.
This is because elements which lie in the same group have same number of valence electrons. Hence, they tend to show same type of reactivity which makes them exhibit similar chemical properties.
For example, Be, Mg, Ca and Sr are all group 2 elements. Hence, they tend to show similar chemical properties.
Thus, we can conclude that out of the given options Be, Mg, Ca elements have properties similar to those of strontium (Sr).
