Leucocytosis is defined as which of the following?

Explanation:
Leucocytosis is an elevation of white blood cells above the normal range. The option that describes a high WBC count best captures this definition, since leucocytosis specifically means the count is higher than normal. Leucocytosis can occur in response to infection, inflammation, stress, or certain medical conditions that stimulate the bone marrow to produce more white cells. The other descriptions don’t fit: a low WBC count is leukopenia, a normal count means no leucocytosis, and a variable count isn’t what leucocytosis refers to.
