Final answer:

The Decarboxylase test reveals that lysine is converted into cadaverine, a biogenic amine, as a result of the decarboxylation process facilitated by the enzyme decarboxylase and PLP cofactor. The correct option is 1).

Step-by-step explanation:

The end product for Lysine in the Decarboxylase test is cadaverine. The test identifies the presence of decarboxylase enzymes that convert lysine into cadaverine through decarboxylation, a reaction that involves the removal of a carboxylic (CO₂) group.

The process is facilitated by a decarboxylase enzyme and a cofactor pyridoxal phosphate (PLP).

This transformation is a part of the process by which toxic amines can be formed in the gastrointestinal tract; however, not all biogenic amines produced through decarboxylation are harmful, as some play beneficial roles in metabolic processes. Option 1) is the correct one.
