**Answer:**

As given Point A is the center of the circle.

We will answer this question by considering all the options.

Option 1. FA : AE [ Both FA and EA are radius of circle .So their ratio can't be equal to 1:2.]

Option 2. CB : FE [ CB is a chord and FE is a Diameter as length of Chord not given, So we can't Predict about their Ratio.]

Option 3: FE : AH [As FE is the Diameter and AH is radius.Diameter = 2 × Radius,So FE : AH=2:1]

Option 4 : AH : FE [Explained above AH: FE=1:2]

Option 5: AH : AD [AH is the radius of the circle and D is any point on AH So their ratio can't be 1:2.]

**Option (d) AH : FE = Radius : Diameter=1:2 is true.**
