Verified step by step guidance

Identify the key characteristics of the granulocyte in question: it is the first to respond to an infection, contains hydrolytic enzymes in its granules, and has phagocytic abilities.

Understand the role of neutrophils in the immune response: Neutrophils are a type of white blood cell that are part of the body's first line of defense against infections.

Recognize that neutrophils contain granules filled with hydrolytic enzymes, which help break down pathogens during phagocytosis.

Differentiate neutrophils from other granulocytes: Basophils and eosinophils have different functions and do not primarily act as the first responders in infections.

Conclude that neutrophils are the correct answer based on their rapid response to infection, presence of hydrolytic enzymes, and phagocytic capability.
