Q: Information: - Nevus cells are a variant of melanocytes. They are larger than typical melanocytes, do not have dendrites, and have more abundant cytoplasm with coarse granules. They are usually located at the dermoepidermal junction or in the dermis of the skin. Dermal nevus cells can be further classified: type A (epithelioid) dermal nevus cells mature into type B (lymphocytoid) dermal nevus cells which mature further into type C (neuroid) dermal nevus cells, through a process involving downwards migration. - Blue nevus ( also known as '' blue neuronevus , '' '' dermal melanocytoma , '' and '' nevus bleu '' ) is a type of melanocytic nevus . The blue colour is caused by the pigment being deeper in the skin than in ordinary nevi . In principle they are harmless but they can sometimes be mimicked by malignant lesions , i.e. some melanomas can look like a blue nevus . - Melanocytes (or ) are melanin-producing neural-crest derived cells located in the bottom layer (the stratum basale) of the skin's epidermis, the middle layer of the eye (the uvea), the inner ear, meninges, bones, and heart. Melanin is the pigment primarily responsible for skin color. Once synthesised, melanin is contained in a special organelle called a melanosome and moved along arm-like structures called dendrites, so as to reach the keratinocytes. - A lesion is any abnormal damage or change in the tissue of an organism, usually caused by disease or trauma. "Lesion" is derived from the Latin word "laesio" meaning "injury". Lesions may occur in plants as well as animals. - A melanocytic nevus (also known as "nevocytic nevus") is a type of lesion that contains nevus cells (a type of melanocyte). Some sources equate the term mole with "melanocytic nevus". Other sources reserve the term "mole" for other purposes. Given the information above, choose from the list below the object entity that exhibits the relation 'subclass of' with the subject 'blue nevus'.
