Detailed Solution

Concept- Use the concept that, in this particular question, the sum of any two 6-digit numbers is maximum if we add the two largest 6-digit numbers and the total of two 6-digit numbers is lowest if we add the two smallest 6-digit numbers to obtain the answer.
As we are all aware, the largest six-digit number is 999999, while the smallest is 100000.
The next step is to determine the maximum and minimum digit numbers for any two 6-digit sums.
Now we are familiar with the idea that adding two of the largest six-digit numbers results in the total of any two six-digit numbers being at its maximum. And if we add the two smallest 6 digit integers, the sum of the two is minimum.
Therefore, we must add the two largest six-digit numbers for the maximum number of digits, and the two lowest six-digit numbers for the least number of digits.
Thus, the sum of the two largest six-digit numbers is

Therefore, the sum of the two largest six-digit numbers has a digit count of 7.
Accordingly, any two 6 digit numbers will only have a maximum of 7 digits added together.
Now,

is the result of adding the two smallest six-digit digits.
Consequently, the sum of the two smallest six-digit numbers has a digit count of 6.
The sum of any two six-digit numbers should always contain at least six digits.
Hence, the correct answer is an option (1).
