There are five Family on the periodic table that are alkali metals , Alkaline earth metals , transition metals , Halogens family and noble gas family.
1) In alkali metals, there are six elements are present and among all the elements Sodium metal should be selected. Because sodium metal is most abundant metal in the world.
- uses of sodium are
- sodium salt are common salt that added to the food to enhance the taste.
- washing soda are made up of sodium salt which is used as water softener.
- sodium salts are also used as buffer to maintain Ph.
2) In alkaline earth metal family, The magnesium element should be selected.
- uses of magnesium are
- since magnesium is a soft metal so it can burn easily therefore it is used in fire works.
- magnesium is also important for proper growth and maintenance of bones.
- Magnesium is light weight metal so it can used to make car seat , luggage and power tools etc.
3) In Halogens gas family , chlorine should be selected.
- Uses of chlorine are
- The chlorine is used in cleaning purpose as it act as bleaching agent.
- Chlorine is also used to prepare the pesticides to removes pest in crops.
- In refrigerators, the cold breeze is coming out is chlorine gas which are used to increase the shelf life of the plants.
4) In transition metals , copper metal should be choose.
- Use of copper metal are
- Copper is highly ductile metal so it drawn into wires and used in various electrical purpose.
- The copper has anti corrosive properties so it can used in making kitchen utensils.
- The copper has anti microbial property so it can used in packaging of food.
5) In noble gas elements, The helium gas should be selected
- uses of helium gas are
- It used as semiconductors.
- It used in party balloons.
- The helium is inert gas so it used to make optical fibers.
These are the daily life usage of all the elements of each family of the periodic table.

The hydrologic cycle is a continuous cycle where water evaporates and travels into the air and becomes part of a cloud and falls down as precipitation and then evaporates again. Then the cycle repeats in a never ending cycle.

I think is b
Explanation:
if im wrong, heres some information:
mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.[1] While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy. This energy propagates in the same direction as the wave. Any kind of wave (mechanical or electromagnetic) has a certain energy. Mechanical waves can be produced only in media which possess elasticity and inertia.
