Solution:

Given number is 54638.

Decreasing each odd digit by 1 and increasing each even digit by 1, we get:

New number = 65749

Now, we need to find the sum of digits of the new number.

Sum of digits = 6 + 5 + 7 + 4 + 9 = 31

But this is not any of the options given in the question.

So, we need to keep reducing the sum by 9 until we get a number that matches one of the options.

31 - 9 = 22

22 is not an option.

22 - 9 = 13

13 is not an option.

13 - 9 = 4

4 is not an option.

4 - 9 = -5

-5 is not a valid answer as the sum of digits cannot be negative.

So, the closest option to 31 is option A, which is 27.

Therefore, the answer is option A) 27.
