Final answer:

Among the options, Neutrophilic leukocytosis is the White Blood Cell (WBC) form that is an ominous finding in the presence of severe bacterial infection, as neutrophils are primarily involved in fighting bacterial infections. Other WBC forms like Eosinophilia, Basophilia, and Lymphocytosis are associated with other immune responses.

Step-by-step explanation:

In the presence of a severe bacterial infection, the ominous finding among the different forms of White Blood Cells (WBCs) is typically Neutrophilic leukocytosis. Neutrophils are the leukocytes found in the largest numbers in the bloodstream, and their primary role is to fight bacterial infections. An excess or proliferation of these neutrophils, also known as leukocytosis, is often associated with bacterial infections, and hence can serve as an indicator of severe infection.

On the other hand, Eosinophilia is associated primarily with parasitic infections while Basophilia and Lymphocytosis are usually related to other immune responses or conditions, not specifically severe bacterial infections.
