The thymus is responsible for the development of functional T cells, so if it fails to develop, functional T cells are absent. This condition is known as Di George's syndrome, which affects multiple organ systems and is characterized by a weakened immune system due to the absence of T cells. Therefore, both options E are correct. The other options are not related to thymus development.
