Detailed Solution

As everyone is aware, the periodic table is an arrangement of all the chemical elements in ascending order of their atomic number, which is the sum of all the protons in an atomic nucleus. The distribution of electrons among the various orbitals is referred to as the "electronic configuration." In a superscript style, it specifies the electrons that are now in the orbital.

We need to know the atomic number of the element that is included in the periodic table in order to get the electronic configuration from the periodic table.
As is common knowledge, the atomic number of an element indicates how many protons there are, which is equal to how many electrons there are.
The sequence in which we must write the element's electrical configuration is as follows.

Remember that the s block receives two electrons, the p block receives six, the d block receives ten, and the f block receives fourteen. We may now write the electrical configuration of the components in accordance with this arrangement.

Hence option (B) is correct.
