Decide Whether the Game Is Strictly Determined A)A's Optimal Strategy Is Q; B's Optimal Strategy Is A;

Decide whether the game is strictly determined. If it is, give the players' optimal pure strategies and the value of the game.
$\begin{array} { l } &B& \\\text { A } &\begin{array} { r } \mathrm { P } \\\mathrm { Q } \\\mathrm { R } \\\mathrm { P }\end{array} \left[ \begin{array} { c c c } a &b& c\\-3&-5&10\\1&1&0\\-1&-2&-3\\1&1&-1\end{array} \right] \\\end{array}$

A) A's optimal strategy is Q; B's optimal strategy is a; value: 0.5
B) A's optimal strategy is P; B's optimal strategy is a; value: 1
C) A's optimal strategy is P; B's optimal strategy is b; value: 1
D) A's optimal strategy is R; B's optimal strategy is c; value: 3
E) The game is not strictly determined
