What is the maximum number of Xs which can
be placed on a 3by3 Tic-Tac-Toe board without
a three-in-a-row in any direction?
a. 4
b. 5
C. 6
d. 7

Answer 1

Step-by-step explanation:

This situation cannot develop in normal play, as you take turns, so even if the other player cooperates by sticking to the single diagonal, they would win on the sixth move, after you have placed any three of the above six Xs. However, you did not ask if this could be done in play.
