How is the modern periodic table organized as one goes across a row from left to right?

Aby decreasing number of valence electrons
Bby increasing number of neutrons
Cby increasing atomic number

Eliminate

Dby increasing atomic mass

So, when we move from left to right in a periodic table then there occurs an increase in atomic number because there occurs an increase in the number of electrons of the atoms.

And, in neutral atoms the number of electrons and number of protons are the same.

Therefore, we can conclude that modern periodic table organized by increasing atomic number as one goes across a row from left to right.
