Answer:

The order is determined as: Be > Mg > Ca > Sr (option B)

Explanation:

The electrons are attracted to the nucleus and it is necessary to provide energy to start them. The ionization energy I is then the energy needed to start an electron to a gaseous atom, isolated and in a fundamental state. The electrons of the last layer are always lost, which are the weakest attracted to the nucleus.

The elements beryllium, calcium, magnesium and strontium, if you place them in the periodic table, are in the same group. In the same group, the size of the atoms increases as they descend in the periodic table. In this way, electrons are found in layers increasingly distant from the nucleus, being less and less attracted to it. This facilitates its extraction from the atom. Finally, the ionization energy decreases as it descends in a group.  Following this criterion, the order is determined as: Be > Mg > Ca > Sr (option B)
