Step 2: Analyzing the options.
(A) 19 to 29: Incorrect, this value is higher than the normal range for serum bilirubin.
(B) 3 to 13: Correct, this is the typical normal range for serum bilirubin levels.
(C) 15 to 25: Incorrect, this is slightly higher than the normal range.
(D) 33 to 37: Incorrect, this range is significantly higher than normal, indicating possible liver dysfunction.
Step 3: Conclusion.
