What is the minimum product-of-sum Boolean expression for the output ‘X’?

A car burglar alarm

has a normally LOW switch on each of its four doors when they are closed. If

any door is opened, the alarm is set off. The alarm requires an active-HIGH

output. What type of logic gate is needed to provide this logic.
