For each of the following action$-$selection methods, indicate which option describes it best.

A: With probability $$p $,$ select$$ argmaxaQ$($s$,$a$).$ With probability $1$p $,$ select a random action. $$p$=0\mathrm{.}99.[$ Select $]["$Mostly exploration", "Mostly exploitation", "Mix of both"$]$

B: Select action a with probability$$P$($a$|$s$)=$eQ$($s$,$a$)$$$a$$eQ$($s$,$a$)$$[$ Select $]["$Mostly exploration", "Mostly exploitation", "Mix of both"$]$

C: Always select a random action. $[$ Select $]["$Mostly exploration", "Mostly exploitation", "Mix of both"$]$

D: Keep track of a count, Ks$,$a$,$ for each state$-$action tuple, $($s$,$a$),$ of the number of times that tuple has been seen and select$$argmaxa$[$Q$($s$,$a$)$Ks$,$a$].[$ Select $]["$Mostly exploration", "Mostly exploitation", "Mix of both"$]$
