The correct option is B Tapetum cellulosum
The tapetum cellulosum is modified choroid and consists of iridocytes.

Tapetum fibrosum is characteristic of ungulates and has organized collagen bundles. Porphyropsin is the retinal pigment of freshwater fishes. Luciferin is pigment found in luminescent algae and causes light production in fire algae.So, the correct answer is option B.
