I don't see the diagram or any other context, so I can't tell which of those four statements is true. Could you either

- upload the figure, or
- describe the configuration (which points are collinear, any right-angle or degree marks, etc.), or
- give coordinates for A, C, D, E?

If you want to check it yourself, here are quick checks you can use once you have the figure:

- ∠CED is the angle with vertex E formed by rays EC and ED. If C, E, D are collinear then ∠CED = 180°. If there is a 45° arc or marking at E between CE and ED then ∠CED = 45°.
- ∠AEC is the angle with vertex E formed by rays EA and EC. If there is a right-angle square marking at E between EA and EC then ∠AEC = 90°. If there is a 45° arc/marking between EA and EC then ∠AEC = 45°.
- If coordinates are given, compute vector directions EC, ED, EA and use the dot product to find the angle: cos θ = (u·v)/(|u||v|).

Send the diagram or a description and I’ll pick the correct statement and show the reasoning.
