• Dimensionless Numbers in Heat and Fluid Transport:
• Péclet Number ($Pe$): Product of Reynolds and Prandtl numbers ($Pe = Re \cdot Pr = \frac{u L}{\alpha}$), representing the ratio of advective transport to thermal diffusion $\rightarrow$ (III)
• Prandtl Number ($Pr$): Ratio of momentum diffusivity to thermal diffusivity ($Pr = \frac{\nu}{\alpha} = \frac{\mu c_p}{k}$) $\rightarrow$ (IV)
• Nusselt Number ($Nu$): Ratio of convective to conductive heat transfer across a boundary ($Nu = \frac{h L}{k}$) $\rightarrow$ (I)
• Stanton Number ($St$): Ratio of heat transferred into a fluid to its thermal capacity ($St = \frac{Nu}{Re \cdot Pr} = \frac{h}{\rho c_p u}$) $\rightarrow$ (II)
• Systematic Match: (A)-(III), (B)-(IV), (C)-(I), (D)-(II) corresponds to Option 3.

Correct option: (3) (A) - (III), (B) - @), (C) - (I), (D) - (IV)
