  • The teeth are secured in the alveolar processes (sockets) of the maxilla and the mandible. 
  • Gingivae (commonly called the gums) are soft tissues that line the alveolar processes and surround the necks of the teeth.
  • Teeth are also held in their sockets by a connective tissue called the periodontal ligament. It is made up of collagen fibres called Sharpey's fibres. 
  • Crown is covered by enamel. Enamel is the hardest part of the human body.
  • Below the enamel, dentine is present. It is secreted by odontoblast cells.
  • Dentine forms the bulk of the teeth.
  • Inside the dentin, pulp cavity is present. 
  • Pulp cavity contains nerves and blood vessels. There are no lymphatic vessels.

Dentine is secreted by odontoblast cells. Hence, the correct answer is option b.
