Q

An elderly woman named Cassidy Boo was experiencing elbow pain for the past three months. Her physician requested blood and
synovial fluid analyses. Blood results came out and it showed negative for the presence of rheumatoid factor and anti-nuclear antibodies.
Synovial fluid results showed decreased glucose level with elevation in WBC count. Moreover, thin needle-like crystals were observed in
her synovial fluid upon microscopy. The said crystals were subjected to polarizing microscopy and were able to polarize light in a
negatively birefringent way.
Which of the following pairings correctly identifies the said crystal and its corresponding clinical significance?
