The correct answer is: **A. heritable "on/off switches" for gene sequences due to environmental factors**.
Epigenetic changes involve modifications that affect gene expression without altering the underlying DNA sequence. These modifications can be influenced by environmental factors and can be heritable, meaning they can be passed down to subsequent generations.
