B) The study of earth atmosphere
C) The science of measuring
D) The study of meteors

Answer 1

The branch of science which deals with study of measurement is termed as metrology. The art of metrology is governed by seven fundamental units and derived units. All the physical quantities require quantification so that it can be accurately analyzed.

Step by step solution
Metrology is the scientific study of measurement. Metrology is divided into three basic overlapping activities. The first being the definition of units of measurement, second the realisation of these units of measurement in practice, and last traceability, which is linking measurements made in practice to the reference standards. These overlapping activities are used in varying degrees by the three basic sub-fields of Metrology. The sub-fields are scientific or fundamental metrology, which is concerned with the establishment of units of measurement, Applied, technical or industrial metrology, the application of measurement to manufacturing and other processes in society, and Legal metrology, which covers the regulation and statutory requirements for measuring instruments and the methods of measurement.

Scientific metrology is concerned with the establishment of units of measurement, the development of new measurement methods, the realisation of measurement standards, and the transfer of traceability from these standards to users in a society. This type of metrology is considered the top level of metrology which strives for the highest degree of accuracy

Applied, technical or industrial metrology is concerned with the application of measurement to manufacturing and other processes and their use in society, ensuring the suitability of measurement instruments, their calibration and quality control.

Legal metrology "concerns activities which result from statutory requirements and concern measurement, units of measurement, measuring instruments and methods of measurement and which are performed by competent bodies.

So option C, Science of measuring

Note: In every country there is the institution and organisation which keep records and standards for unit of measurement and coordinate with other nations to maintain it to develop international standards.
