The points and are such that if
are in A.P.
Explanation for the correct option:
Step 1: Compute the required distances
In the question, Three points and are given.
Compute the distance between and .
Compute the distance between and .
Step 2: Find the relation between distances
Since, it is given that .
So, .
This implies that, and are in A.P.
Therefore, If the points and are such that , then and are in A.P.
Hence, option is the correct answer.
