Explanation

Microbiology is the scientific study of microorganisms—living organisms that are too small to be seen with the naked eye, including bacteria, viruses, fungi, and protozoa.
The term originates from the Greek words mikros (small), bios (life), and logos (science).
While the option 'The science of living organisms' technically defines the broader field of Biology, it is the best and most encompassing choice among the given options, as microbiology is a fundamental branch of biology.

Option B: This option describes the primary focus of Pathology, which is the science of the causes and effects of diseases, especially the branch of medicine that deals with the laboratory examination of samples of body tissue for diagnostic or forensic purposes.
Option C: This option defines Hematology, the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood.
Option D: This is a very general and somewhat vague phrase. The study of diseases is more accurately termed Pathology or Nosology. While microbiology is crucial for understanding infectious diseases, this option does not accurately define the entire field.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition of Microbiology as background academic context rather than a clinical decision trigger.
A nurse's understanding of microbiology is fundamental to patient safety, primarily through infection prevention and control (IPC) practices like hand hygiene, aseptic technique, and sterilization.
Knowledge of different pathogens and their modes of transmission allows nurses to implement appropriate isolation precautions (e.g., contact, droplet, airborne) to prevent nosocomial (hospital-acquired) infections.
What if? If a patient develops a hospital-acquired infection with a multi-drug resistant organism (MDRO), a nurse's microbiology knowledge becomes critical for understanding the specific contact precautions required, educating the family, and monitoring the effectiveness of specialized antibiotic therapy.

How to Approach the Question

First, identify the key term in the question, which is 'Microbiology'.
Recall the definition of this term. Microbiology is the study of microscopic organisms.
Evaluate each option against this definition.
Option A, 'The science of living organisms,' is a broad definition for Biology, but microbiology is a part of it. Consider if other options are more specific or more incorrect.
Option B refers to diagnosis (Pathology), Option C refers to blood (Hematology), and Option D is a vague reference to disease.
Conclude that while Option A is broad, it is the only one that correctly places microbiology within the study of life, making it the best choice among the flawed options.
