Cognitive changes in the body refer to changes in areas such as memory, problem solving, and decision making. During late adulthood, these changes are expected to occur as a natural part of aging. Option A, completely stabilized, is incorrect because even though some cognitive abilities may remain stable, others are likely to decline. Option B, at their peak, is incorrect because peak cognitive abilities happen in early adulthood. Option D, increasing significantly, is incorrect because cognitive changes in late adulthood are typically gradual and may even plateau at some point. Therefore, the most accurate option is C, mildly declining, as it reflects the typical pattern of cognitive changes in late adulthood.
