C. part C = dynamic pressure is correct.

In Bernoulli’s equation, the dynamic pressure term corresponds to \(\dfrac{\rho v^2}{2}\)​, which represents the kinetic energy per unit volume of the fluid.

B. Darcy's equation

Darcy’s equation (or Darcy’s law) is used to predict and describe fluid flow through porous media.

(A) \(F(s)=\int\limits_{0}^{\infty }{f(t){{e}^{-st}}dt}\)

This is the standard definition of the Laplace transform for a time-dependent function f(t)f(t).

B. \(G = \dfrac{V \times P}{P + p}\)

This is the Langmuir isotherm equation used to estimate the amount of gas stored in shale.

B. drawworks

The drawworks is an essential part of the hoisting system, used to raise and lower the drill string and casing.

D. To reciprocate the drill string up and down

Reciprocating the drill string is not a function of the rotary table; it is primarily used for rotation, not vertical movement.

B. Cleveland (open cup type)

The flash point of atmospheric distillation residue is typically determined using the Cleveland open cup apparatus.

A. Deoiling

Deoiling is not a major refining process for upgrading lubricating oil quality; processes like clay treatment, hydrotreatment, and solvent refining are more important for that purpose.

B. Atmospheric gas oil.

That would mean in this context, atmospheric gas oil is considered to have the maximum API gravity among the listed fractions.

C. Water

For water, the pour point and freezing point are effectively the same, at 0∘C0^\circ\text{C} under standard conditions.
