The table below shows the number of items ordered from a bakery for the Smith family reunion.

Which number sentence and answer shows the number of items ordered for the Smith family reunion?

$1^{2} + 12^{2} + 6^{2} + 5^{2} + 20^{2} = 606$

$1^{2} + 12^{2} + 6^{2} + 5^{2} + 20^{2} = 1, 906$

$1^{2} + 12^{2} + 6^{2} + 5^{2} + 20^{2} = 44^{2} = 1, 606$

$1^{2} + 12^{2} + 6^{2} + 5^{2} + 20^{2} = 888$
