The correct answer is: A. log-log plot of friction factor against Reynolds number.
A Stanton diagram is a log-log plot of friction factor against Reynolds number. It is used to determine the friction factor for a given flow condition. The friction factor is a dimensionless number that is used to calculate the pressure drop in a pipe. The Reynolds number is a dimensionless number that is used to characterize the flow of a fluid.
The Stanton diagram is a useful tool for engineers who design and operate pipes. It can be used to determine the pressure drop in a pipe for a given flow condition. The Stanton diagram can also be used to determine the friction factor for a given pipe and flow condition.

Here is a brief explanation of each option:
- Option A: log-log plot of friction factor against Reynolds number. This is the correct answer. The Stanton diagram is a log-log plot of friction factor against Reynolds number. It is used to determine the friction factor for a given flow condition. The friction factor is a dimensionless number that is used to calculate the pressure drop in a pipe. The Reynolds number is a dimensionless number that is used to characterize the flow of a fluid.
- Option B: log-log plot of relative roughness against Reynolds number. This is not the correct answer. The Stanton diagram is not a log-log plot of relative roughness against Reynolds number.
- Option C: semi-log plot of friction factor against Reynolds number. This is not the correct answer. The Stanton diagram is not a semi-log plot of friction factor against Reynolds number.
- Option D: semi-log plot of friction factor against relative roughness. This is not the correct answer. The Stanton diagram is not a semi-log plot of friction factor against relative roughness.
