C. Class II Div 2

D. Class III

The correct answer is B. Class II Div 1.

Class I Incisor Relationship

Lower incisal edges occlude with or lie immediately below the cingulum plateau of the upper incisors.

Class II Incisor Relationship

The lower incisal edge lies posterior to the cingulum plateau of the upper incisors.

Class II Division 1 Incisor Relationship : The upper central incisors are proclined or of average inclination. There is an increase in overjet.

Class II Division 2 Incisor Relationship : The upper central incisors are retroclined. The overjet is usually minimal but may be increased.

Class III Incisor Relationship: The lower incisal edges lies anterior to the cingulum plateau of the upper incisor.
