B Correct answer
Explanation

A1C (glycated hemoglobin) measures average blood sugar levels over the past 2-3 months by detecting glucose attached to hemoglobin. Unlike a finger-prick test which shows current sugar, A1C reflects longer-term glucose control. The other options are unrelated - sperm count is tested through semen analysis, blood group through antigen typing, and HIV through specific viral antibody/antigen tests.
