Question

Match List-I with List-II

Choose the correct answer from the options given below:

• (A) - (II), (B) - (IV), (C) - (V), (D) - (I), (E) - (III)
• (A) - (I), (B) - (III), (C) - (II), (D) - (V), (E) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III), (E) - (V)
• (A) - (IV), (B) - (I), (C) - (V), (D) - (III), (E) - (II)

Hint:

Always start matching the most straightforward terms first:
An Ideal fluid has no viscosity (A matches with I). This immediately narrows down your choices in many multiple-choice formats.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Fluids are classified based on their viscosity and their behavior under applied shear stress.

Step 3: Detailed Explanation:
Let us match the fluid types with their corresponding characteristics:
1.

Ideal fluid (A): A fluid that has zero viscosity and is completely incompressible. Thus, it matches with characteristic

(I).
2.

Newtonian fluid (B): Obeys Newton's law of viscosity, which states that shear stress is directly proportional to the rate of shear strain. Thus, it matches with characteristic

(II).
3.

Real fluid (C): A real fluid always possesses a finite viscosity. Thus, it matches with characteristic

(IV).
4.

Non-Newtonian fluid (D): Does not obey Newton's law of viscosity, meaning shear stress is not proportional to the rate of shear strain. Thus, it matches with characteristic

(III).
5.

Ideal plastic fluid (E): Requires a certain yield stress threshold before initiating flow, after which shear stress is proportional to the rate of shear strain. Thus, it matches with characteristic

(V).
This yields the matching set: (A) - (I), (B) - (II), (C) - (IV), (D) - (III), (E) - (V).

Step 4: Final Answer:
The correct option is 3, which corresponds to (A) - (I), (B) - (II), (C) - (IV), (D) - (III), (E) - (V).
