At the interface of two fluids, there is a difference in pressure. This leads to the existence of a surface force, the surface tension, that shapes the fluid.

The surface tension of water is roughly 72 dynes/cm,

However, that is highly dependant on the characteristics of the considered material (physical and chemical), and thus all fluids (and thus liquids) do not have the same surface tension.

Without a large portion of us never paying consideration on it, surface tension is acting surrounding us, all around and constantly, influencing our day by day life in various ways. Truth be told it is surface tension that keeps the billions of cells in our body utilitarian, guaranteeing the best possible association of their biomolecules, into films and different sorts of cell organelles. Surface tension is a genuinely major property of water, making it a perfect medium taking into account for life as we probably aware it is existing. Speaking of a better effectively available scale, well known to every one of us, it is surface pressure or tension that makes water drops circular.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust. the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles. three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
