A. Standard initiative
B. Sponsored initiative
C. Standard international
D. Sponsored international

Answer 1

Hint: Recall the name of an internationally standardised system which gives a common language between nations and between the different branches of science and technology.

Complete step by step answer:
The metric system began as the legal system of measurement in France during the 1800’s. It was designed to replace the misunderstood and mixed-up units which were used at that time.
S.I. (abbreviated from the French Système International d‘unités) which means ‘International system of units’ adopted by the General Conference on Weights and Measures - the sixth conference since 1840. The International System was a modern form of the metric system.
Hence, the correct option is C, i.e., Standard international

Additional Information:
The advantage of the S.I. system of units is its simplicity.
Any measured property has a unit that is a combination of some of the seven base units.
Larger and smaller multiples of these units are defined by multiplying powers of ten. The names of these units are derived from the base unit through the use of prefixes.
7 base units of S.I. system:
i) metre (length)
ii) kilogram(mass)
iii) second (time)
iv) ampere (electric current)
v) kelvin (temperature)
vi) candela (luminous intensity)
vii) mole (amount of substance)

Note: Students should understand the different systems of measurement and their full form. S.I. is one of them and most frequently used. The other popular measurement systems are M.K.S., C.G.S. and F.P.S. Students also need to know the methods of conversion from one system to another system.
