Answer: B. Christmas Tree Cataract
Explanation: A Christmas tree cataract is a rare age-related change resulting from accelerated breakdown of membrane-associated denatured proteins induced by elevated calcium levels. The peptides and amino acids accumulate in the lumen of the reticular meshwork, and cysteine is concentrated beyond the level of crystallisation causing the formation of needles, that impart the fascinating appearance of a Christmas tree in the eye. Christmas tree cataracts have also been seen in patients with myotonic dystrophy.
