New species appear relatively quickly are associated with the theory of . (a) punctuated equilibrium. So option (a) is the correct answer.
A pattern of rapid evolutionary change followed by long periods of stagnation is a pattern explained by an interrupted equilibrium. Punctuation equilibrium states show that organisms do not change much as they appear in the fossil record.
Interrupted equilibrium predicts that many species evolutionary changes occur on short time scales associated with speciation events.
An intermittent equilibrium occurs as genetic variation passes more rapidly, increasing the rate of evolution and speciation. Tyrannosaurus fossils and mollusks species from the Turkana Basin are examples of intermittent equilibrium.

I believe the correct answer to be A hypothesis must be testable for it to be useful in scientific research because a hypothesis is an educated guess on what is going to happen during your experiment/ scientific research.
The sentence is: The International system of units is the most popular unit of measurement of the fundamental quantities which are used in the fields of science and engineering.
What is the international system of units?
The international system of units or SI units refers to units of measurements which is based on the meters as unit of length, kilogram as unit of mass , and seconds ad the unit of time.
The SI unit is also called the metric system.
The international system of units is comprised of seven basic units of the seven fundamental quantities as well as other additional quantities derivedfrom the fundamental quantities.
In conclusion, the international system of units is the worlds most used system of measurement.
