An automated emergency sprinkler system in a chemical processing plant activates if both the primary heat sensor registers a temperature above 120∘C120^\circ\text{C}120∘C and the vessel pressure exceeds 5 bar5\text{ bar}5 bar, or if the manual emergency lever is pulled.

This system's operation can be represented by the boolean inputs:

  • HHH: Primary heat sensor registers above 120∘C120^\circ\text{C}120∘C
  • PPP: Vessel pressure exceeds 5 bar5\text{ bar}5 bar
  • MMM: Manual emergency lever is pulled

The logic rule determining system activation is written as: (H and P) or M(H\text{ and }P)\text{ or }M(H and P) or M

Complete the truth table by identifying the missing binary values for [A], [B], [C], [D], [E], and [F].
