D Correct answer
Explanation

Both D-serine and D-aspartate are naturally occurring D-amino acids found in mammalian brain tissue, functioning as neuromodulators and neurotransmitters. D-serine acts as a co-agonist at NMDA receptors, while D-aspartate regulates hormone release. D-alanine is not typically found in brain tissue.
