The correct answer is d) Hepatocellular adenoma.
Hepatocellular adenoma (HCA) is a benign liver tumor that can demonstrate signal loss on out-of-phase (opposed phase) MRI due to the presence of intracellular lipid or fat. This is because the opposed-phase sequence is sensitive to the presence of fat, which can cause signal loss.
