1."press"(a)
'You' takes the base form 'press'. This describes how a device always works — a standard instruction.
2."goes off"(b)
'My alarm' is third person singular → 'goes off'. This describes the speaker's daily habit.
3."leave"(c)
'You' takes the base form 'leave'. This is a chemistry fact about corrosion.
4."gets"(d)
'My boss' is third person singular → 'gets'. The word 'always' emphasizes this is a habitual reaction that happens every single time, not a one-time prediction. Zero conditional is used for predictable, repeated behaviors.
5."close"(b)
'Unless' already means 'if...not', so use the affirmative form 'close'. 'Unless you close' = 'If you don't close'.
