Solution

The answer is the fourth one: 12,000 cells per microliter.

Explanation:

Leukocytosis is a condition characterized by an elevated number of white blood cells (WBCs) in the blood.
Normal WBC count ranges from approximately 4,000 to 11,000 cells per microliter.
A WBC count above this range indicates leukocytosis.

Let's evaluate each option:

1200 cells per microliter: This is below the normal range and indicates leukopenia, not leukocytosis.
1800 cells per microliter: This is also below the normal range and indicates leukopenia.
5000 cells per microliter: This is within the normal range.
12,000 cells per microliter: This is above the normal range and indicates leukocytosis.

Therefore, a WBC level of 12,000 cells per microliter would indicate that a patient has leukocytosis.
