  1. Sutures

  2. Fontanelle

  3. Symphasis

  4. gap junctions


Correct Option: B
Explanation:
An infant's skull is made up of 6 separate cranial (skull) bones:
  • Frontal bone
  • Occipital bone
  • Two parietal bones
  • Two temporal bones
These bones are held together by strong, fibrous, elastic tissues called sutures. Also, the soft spaces between the bones that remain open in babies and young children are called fontanelles. Sometimes, they are called soft spots. These spaces are a part of normal development. 

So, the correct option is 'Fontanels'.
