D Correct answer
Explanation

Let the present age of father be x years.

Five years ago, father's age = x - 5 years

Now, according to question,

x - 5 = 30

x = 35 years

So, father's present age = 35 years

So, son's present age = 35 - 23 = 12 years 

Now, total age of father and son after 10 years = (35 + 10) + (12 + 10) = 67 years
