Although I picked A, but it took me 3 mins
Word problems are difficult in expressing words to math equation.
My solution is
T = total population
X = total support war
-> 0.2 X = support + no military experience
-> 0.8 X = support + have military experience = 0.04T (4% of population support + have M.experience)
So 0.8X = 0.04T -> X/T = 0.04/0.8 = 5%
A is correct.
Please +1 KUDO if my post helps. Thank you.
