Answer: C.retinal neovascularization
Explanation: Retinitis pigmentosa is a bilateral, symmetric, progressive disease that starts in early adult life. The inheritance pattern may be autosomal dominant or recessive, X-linked, digenic, mitochondrial, or sporadic. Night blindness, bone-corpuscular retinal pigmentation, a pale, waxy disk, attenuation of retinal blood vessels, and a posterior subcapsular cataract are characteristic. Cystoid macular edema also may be present.
