Explanation / Answer

Ans is A

Nash equilibrium is a situation where there is no incentive for any player to change their strategy given the strategy of other player.

Thus if nash equilibrium is given then 1st will always follow.

Secondly if one firm deviate and doesnot advertise then definitely he will loose otherwise advertising wouldnot have been a nash equilibrium.

If both stop advertisement then both can save their advertising cost and their market share will remain same. Thus leading to more profit.
