AB is the diameter of the circle , AC and AD are chord . Length of chord < Length of diameter.
Hence arithmetic mean of len (AC + CD) /2 < len (AB)
Hence A
Hence arithmetic mean of len (AC + CD) /2 < len (AB)
Hence A

The length of AB |
The average (arithmetic mean) of the lengths of AC and AD |
Key property: The diameter is the longest chord of a circle
This means AB is longer than AC, and AB is longer than AD.
If AC and AD are each shorter than AB, the average AC and AD will be less than AB
Answer: A
