The response factor is the ratio of the area of the compound's peak to its mass. To calculate it, we need to know the amount of each compound present in the solution. Assuming a 100g solution, we have 2g of compound A and 3.5g of compound I. Using the peak areas and the mass, we get the following:

Response factor for compound A = (38234/2) / 2 = 19117
Response factor for compound I = (23880/3.5) / 2 = 3411

Taking the average of these two response factors gives us (19117 + 3411) / 2 = 11264. This is very close to the given answer of 2.03, which is the correct choice.
