Accepted Answer

Epigenetic events can occur well after development is over. This is known as epigenetic plasticity, where the epigenome can be altered by environmental changes and affect gene expression even in adulthood. Option A is incorrect as not all development adjustments are epigenetically controlled. Option B is incorrect as epigenetic changes can sometimes be maladaptive. Option D is incorrect as developmental adjustments are not necessarily transgenerational. Option E is incorrect as epigenetic adjustment and developmental adjustment are not interchangeable terms.
