• A. Hyperplasia
• B. Hypertrophy
• C. Splenomegaly
• D. Hyperparasitism

Hint:

Hypertrophy = Increase in cell size Hyperplasia = Increase in cell number Splenomegaly = Enlargement of spleen

Answer 1

The Correct Option is B

Concept: Biology uses specific terms to describe increase in cell size, increase in cell number and enlargement of organs. These terms should not be confused with one another.

Step 1: Understand the meaning of Hypertrophy.
Hypertrophy means \[ \text{Increase in size of existing cells} \] without increasing their number.

Step 2: Understand the meaning of Hyperplasia.
Hyperplasia means \[ \text{Increase in number of cells} \] Therefore Hyperplasia does not refer to increase in cell size.

Step 3: Understand the meaning of Splenomegaly.
Splenomegaly means \[ \text{Enlargement of spleen} \] and has no relation with increase in RBC size.

Step 4: Apply the definition to the question.
The question states that RBC size increases. Increase in size of a cell is called \[ \boxed{\text{Hypertrophy}} \]

Step 5: Select the correct answer.
Hence, \[ \boxed{\text{Option (B)}} \] is correct.
