A

gas constant

B

ideal gas ratio

C

universal gas law

D

reciprocal gas factor

Understanding the Answer

Let's break down why this is correct

R is the gas constant, a fixed number that connects pressure, volume, temperature, and moles. Other options are incorrect because Thinking R is an "ideal gas ratio" is a mix‑up of what a ratio means; Calling R the "universal gas law" confuses the name of a constant with the name of a law.
