Choice A rationale:

Discarding possessions easily, regardless of their value, is not characteristic of hoarding disorder. Hoarding disorder involves the persistent difficulty in parting with possessions, even if they have little value, due to the emotional attachment individuals feel toward these items.

Choice B rationale:

Accumulating possessions without any emotional attachment is not indicative of hoarding disorder. In hoarding disorder, emotional attachment to possessions is a hallmark feature, and individuals often experience distress at the thought of discarding items.

Choice C rationale:

This is the correct choice. Hoarding disorder is characterized by the strong need to save items, regardless of their practical value, and the significant distress experienced when attempting to discard them. This behavior leads to the accumulation of possessions and can result in living spaces becoming cluttered and uninhabitable.

Choice D rationale:

Organizing possessions meticulously to maintain a clutter-free environment is not consistent with hoarding disorder. People with hoarding disorder struggle with organization and often have difficulty maintaining clutter-free spaces due to the accumulation of possessions.
