The correct answer is A. Maxilla.

MNTI is an uncommon osteolytic, pigmented neoplasm, primarily affecting the jaws of new born infant. Its origin is linked to neural crest cells. More than 90% occur in the head and neck region especially the anterior part of the maxillary ridge. They appear as rapidly growing, non-ulcerated, darkly pigmented lesions, with a radiographic appearance of an invasive malignant neoplasm.
