The correct answer is A) causes irreversible damage to eye tissue. Tert-butylamine is a highly corrosive chemical that can cause severe eye damage, including irreversible corneal opacity and blindness, if exposed. This is due to its strong alkaline nature, which can rapidly break down and destroy eye tissues. The other answer choices are incorrect - tert-butylamine can be absorbed through the skin, but this is not the major health hazard, it is not an unstable product, and while it may react with some protective gear, this is not the primary safety concern.
