Question

Match List-I with List-II:

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

Hint:

Associate scientists with their key contributions: Bernoulli (fluid), Helmholtz (acoustics), Kepler (motion), Prandtl (aerodynamics).

Answer 1

The Correct Option is D

Daniel Bernoulli is associated with Hydrodynamics. Helmholtz contributed to acoustics. Kepler is linked to mechanics. Ludwig Prandtl developed aerodynamic theory.

Answer 2

Elimination approach:
Any pairing that assigns Kepler to hydrodynamics or aerodynamics is historically wrong, since Kepler is known for laws of planetary motion (mechanics), not fluid flow. Similarly, Bernoulli's principle is the foundation of hydrodynamics (fluid pressure-velocity relationships), so pairing him with acoustics or aerodynamics can be ruled out. Helmholtz made foundational contributions to the physics and mathematics of acoustics, while Ludwig Prandtl developed boundary-layer theory, the basis of modern aerodynamics. Matching each scientist strictly to his historically correct field leaves only (A)-(I), (B)-(III), (C)-(II), (D)-(IV) as fully consistent.
