, will be
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
B
Let the equation of lines represented by 
be 
and 
and one diagonal AC be 
Therefore 
and 
Now on solving the equation of OA and OC with the line AC , we get the coordinates of
and 
Now find the coordinates of mid-point of AC and the equation of diagonal through this mid-point and origin. The required equation is 
.
