D)The relationship cannot be determined from the information given.
Draw a triangle ABCD with AB = CD = 100 and BC = AD = 80
Let us assume that Ann lives at the vertex A, and her three children at just about the vertices B, C, and D
Distance = (Less than 100) + (Less than \(\sqrt{100^2 + 80^2}\)) + (Less than 80)
Distance = Less than (100 + 128.06 + 80) = Less than 308.06
How less? It could be 305 or 290
Hence, option D
