Which of the following statements related to the modern periodic table is incorrect?
a.The `p`-block has `6` columns, because a maximum of `6` electrons can occupy all the orbitals in a `p`-shell.
b.The `d`-blocks has `8` columns, because a maximum of `8` electrons can occupy all the orbitals in a `d`-subshell.
c.Each block contains a number of columns equal to the number of electrons that can occupy that subshell.
d.The block indicates value of azimuthal quantum number `(l)` for the last subshell that received electrons in building up the electronic configuration.
