B Correct answer
Explanation

The fibrous membrane, forming the cranial vault before ossification, is unossified at the angles of the parietal bones, leaving six fonticuli (fontanelles), two medians (anterior and posterior) and two lateral pairs (sphenoidal and mastoid). The anterior fontanelle is the largest. The anterior fontanelle is triangular in shape.
