Inter transitional stage refers to:

A. Stage of eruption of first permanent molar to  4 to 5 years age

B. Stage of eruption of molars at 6 to 8 years of age

C. Stage where 12 primary and 12 permanent teeth are present in the oral cavity

D. Stage of eruption of permanent canine and premolars

The correct answer is C. Stage where 12 primary and 12 permanent teeth are present in the oral cavity

Mixed dentition period is classified into three phases:

1. First transitional period (6 to 8 years of age)

- emergence of first permanent molars

- exchange of deciduous incisors with permanent incisors

2. Inter transitional period (lasts for around 1.5 years)

- relatively stable phase with no changes occurring in the dentition

- teeth present are permanent incisors and first molars and deciduous canines and molars (so 12 primary and 12 permanent teeth are normally seen in this stage)

3. Second transitional period (9-10 year of age)

- Starts with shedding of posterior teeth

- Emergence of canines, premolars and second permanent molars

- correction of ugly duckling stage
