Answer: Option (b)

Explanation:  

• Adult humans have 32 permanent teeth, and consists of four incisors on each jaw, followed by 2 canines, four premolars, and 6 molars.
• Out of the 6 molars, 4 are considered to be Wisdom teeth that grow at the last of each row of the jaw, and at times do not develop until the human is well into their adulthood.
