x,\;y,\;z

are in AP and

{\tan ^{ - 1}}x,{\tan ^{ - 1}}y

and

{\tan ^{ - 1}}z

are also in AP, then

View answer and explanation

Correct option: A

x = y = z

Option A is correct because if x, y, and z are in AP and their inverse tangents are also in AP, then the only solution is when x = y = z.
