GMAT Club Official Explanation:
Given:
- 2x people between Homer and Marge
- 5x people behind Homer (including Marge)
- 9x people ahead of Marge (including Homer)
The total number of people in the line can be expressed as: 9x + 5x - 2x = 12x. Since this should be fewer than 100 people, we get 12x < 100, which gives x < 8.something. Since x must be a positive integer, the maximum value for x is 8, making the maximum number of people in the line equal to 12x = 96. Thus, the maximum number of people behind Homer would be 5x = 40. Therefore, Homer is 96 - 40 = 56th in the line.
Therefore, the maximum number of people that could be ahead of Homer is 55.
Answer: D.

Let people in front of Homer be 'a', between homer and Marge be 'b' and behind Marge is 'c'
Also let people behind homer be B and ahead of marge be A.
So, we know b:B:A = 2:5:9
Let b=2k, B=5k and A=9k
then we know, a= A-(Homer+b) = 9k -(1+2k) = 7k-1
and c= B-(b+Marge) => c= 5k-(2k+1) => c=3k-1
Now we also know a+Homer+b+Marge+c<100 = > k<100/12
So, to maximize a we need maximum k possible which is k=8
THerefore, a= 7k-1 = 7*8-1 = 55
Answer: Option D
