Correct option is B
High oxygen tension causes abnormal retinal vessel proliferation → fibrosis and detachment → retinopathy of prematurity (ROP), a preventable cause of blindness.
Explanation of options: (a) ✘ NEC is related to hypoxia/ischemia, not hyperoxia. (b) ✔ Correct; high O₂ → retinal neovascularization → ROP. (c) ✘ BPD is linked to prolonged ventilation/barotrauma. (d) ✘ IVH is due to fragile germinal matrix, not oxygen therapy.
