If the maximum and minimum temperatures at a place on a day are measured as $44^{\circ} \mathrm{C} \pm 0.5^{\circ} \mathrm{C}$ and $22^{\circ} \mathrm{C} \pm 0.5^{\circ} \mathrm{C}$ respectively, then the temperature difference is

$22^{\circ} \mathrm{C} \pm 1^{\circ} \mathrm{C}$

$22^{\circ} \mathrm{C} \pm 0.5^{\circ} \mathrm{C}$

$22^{\circ} \mathrm{C} \pm 0.25^{\circ} \mathrm{C}$

$22^{\circ} \mathrm{C} \pm 1.5^{\circ} \mathrm{C}$
