(a) 10 - 20
(b) 6 - 8
(c) 9 - 1
(d) 0 - 2
Correct Answer: (b) 6 - 8
Explanation:
As humans, we have two sets of teeth that erupt during our lifetime – the first set is called milk teeth, primary teeth, temporary teeth, deciduous teeth, or baby teeth and they start erupting when we are 6 months old and the next set of teeth, called permanent teeth, begin erupting as we turn 6 years old.
