Solution:

Keep in Mind, when two shapes or polygons are similar , the ratio of their areas is equal to square of their corresponding sides or edges.

As given, Ratio of the edges of two solids = \frac{4}{5}

Ratio of their Surface areas

= ( Ratio of the edges of two solids)²=(\frac{4}{5})^2

=\frac{16}{25}

Option A: 16: 25 is true.
