Geometry

Question Analysis:
This question focuses on diagonal properties in a parallelogram.
The main focus is on understanding that diagonals bisect each other.

Key Concept Explanation:
In any parallelogram, diagonals intersect and bisect each other.
That means each diagonal is cut into two equal segments at the point of intersection.

Step-by-Step Solution:
Diagonal AC is bisected by BD, so point E is the midpoint of AC
→ Therefore, AE = EC

Option Analysis:
A. AE = AB → Not true in general.
B. ✅ AE = EC → Always true by definition of diagonal bisection.
C. AE = DE → ...
