Haematology studies blood, blood-forming organs, and related diseases such as anemia and leukemia. It includes diagnostics like blood counts and coagulation tests. Pathology more broadly addresses disease mechanisms, dermatology covers skin, and “Entramology” is not a recognized specialty. Therefore, haematology is correct.
Graphology claims to analyze personality through handwriting features such as slant and pressure. While scientifically contested, the term clearly refers to handwriting. Shell composition is conchology, geomagnetism concerns Earth’s field, and psephology studies elections. Therefore, A is correct.

In an experiment, the factor deliberately changed by the scientist is the
The independent variable is manipulated to test its effect on the dependent variable. Controlled variables remain unchanged to ensure fairness. This distinction helps identify cause-and-effect relationships.
A controlled experiment isolates a single independent variable to determine its effect. All other factors are kept constant. This ensures reliable results and reduces confusion caused by multiple influences.

A testable prediction made before conducting an experiment is called a
A hypothesis is a tentative statement predicting what might happen in an experiment. It is testable and forms the basis for investigation. If supported by evidence, it can lead to theories or laws.

A well-tested explanation for a wide range of observations is called a
In science, a theory is a comprehensive explanation supported by significant evidence. It explains patterns and predicts outcomes. Unlike a hypothesis, which is a testable guess, a theory has been repeatedly validated.

The process of asking questions and testing ideas is known as
The scientific method is a structured approach involving observation, hypothesis, experimentation, and conclusion. It ensures reliability and reduces bias in results. Unlike guesswork, it relies on evidence and logical reasoning.
