Brunauer Emmett Teller (BET) theory aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique for the measurement of the specific surface area of materials. The observations are very often referred to as physical adsorption or physisorption.

The Brunauer-Emmett-Teller (BET) method is commonly applied to calculate the specific surface area on the basis of nitrogen adsorption isotherm.

The correct answer is A.

BET is used to determine the surface area and pore size distribution.

Yes, I agree @Sourav.

Its pore area not surface area.

It's used to analyse, it doesn't measure the surface area directly.

BET (Brunauer, Emmett and Teller) the specific surface area of a sample is measured " including the pore size distribution. This information is used to predict the dissolution rate, as this rate is proportional to the specific surface area. Thus, the surface area can be used to predict bio availability. So, I think option A is correct.

Yes, I agree on @Tammy Allison.
Option D is correct.
Option D is correct.

The BET theory (abbreviated from Brunner-Emmett-Teller theory) is used to measure the surface area of solid or porous materials.
