Simple problem...

The last digir of this summation should be $6$ which is provided only by the option $\color{#69047E}{\boxed{9553396}}$ .

There are two routes:

Route $1$ a:

$9542613 + 10783 = \fbox{9553396}$

Route $1$ b:

$9542613 + 10783 = \fbox{9553396}$

Since the last digit is $6$ , the third option is the answer.

Route $2$ :

$3 + 3 = 6$

Since the last digit is $6$ , $\fbox{9553396}$ , the third option, is the answer.

Simply find the sum of the units digits which is 6 no other option except 9553396 has 6 in unit,s place so answer is $\boxed{9553396}$

sum of units place give 6 and no other options have 6 at units place
