The correct option with respect to the Pauling electronegativity values of the elements is
As we move across a period, the effective nuclear charge increases leading to decrease
in atomic size and increase in electronegativity.
As we move down the group, the force of attraction decrease between the valence shell
electron due to addition of inner shell. This results into increase in size and decrease in
electronegativity.
| Period No. | Group 13 | Group 14 | Group 15 | Group 16 |
| 3 | Al | Si | P | S |
| 4 | Ga | Ge | Se | |
| 5 | Te |
Hence Option 3 is correct.
