Development of coronoid process of mandible occurs at:

 # Development of coronoid process of mandible occurs at:

A. 10-12 weeks 

B. 12-16 weeks

C. 10-14 weeks 

D. 14-16 weeks

The correct answer is C. 10-14 weeks.

The development of the coronoid process of the mandible occurs during the embryonic period of gestation. Specifically, it takes place between 10 and 14 weeks of gestation. Therefore, the correct option is C. 10-14 weeks.

During this time frame, the mandible undergoes various developmental processes, including the formation of the mandibular body, the ramus, and the coronoid process. The coronoid process is a bony prominence located on the anterior aspect of the ramus of the mandible. It serves as an attachment site for muscles involved in chewing and jaw movement.

Options A and B (10-12 weeks and 12-16 weeks) and Option D (14-16 weeks) do not accurately represent the developmental period when the coronoid process of the mandible forms. The correct time frame is 10-14 weeks.
