Correct answer: B — Mild cognitive impairment

Objective mild cognitive impairment without loss of independence in daily function is consistent with mild cognitive impairment rather than dementia. Dementia requires functional decline, delirium is acute, severe depression needs mood syndrome, and normal pressure hydrocephalus would include gait and urinary features. Functional impact is the discriminator between MCI and dementia.
