$($a$)$ For which citizen i does P strictly dominate H$?$ In other words, for which i is BRi $=\{$P$\}.($b$)$ Assuming that everybody avoids strictly dominated strategies, for which citizens i is P the unique best response? In other words, for which i is BR$2$ i $=\{$P$\}.($c$)$ For which i is BR$3$ i $=\{$P$\}?($d$)$ Is this game dominance solvable?
