The ratio of bases of two triangles is `x : y` and that of their areas is `a : b`. Then the ratio of their corresponding altitudes will be (a) `a x : b y` (b) `a/x : b/y` (c) `a y : b x` (d) `x/a : b/y`

The ratio of base of two triangles is x:y and that of their areas is a: b. Then the ratio of their corresponding altitudes will be:
