Organic Chemistry is defined as the Chemistry of Compounds of Carbon.
Here are the first five Groups:
1) Carboxides [CO and CO2];
2) Hydrocarbons [HC];
3) Carbohydrates [HCO];
4) Proteins [HCON];
5) Nucleotides [HCONP].
There are entire classes of chemical compounds composed of organic (carbon bearing) molecules. Hydrocarbons are a major class, and they include molecules such as ethane, methane, propane, pentane hexane and so on.
alkanes, alkenes, alkynes, ketones, benzenes, phenols
The answer choices were not provided. An example of a group that has organic compounds are C6H6, C2H5OH, C6H5CH3, and C3H5(NO3)3.
In the human body, the four most important groups of organic compounds are carbohydrates, lipids, proteins, and nucleic acids (such as RNA and DNA).
The organic compounds, of course, as saccharides, alkanes,
lipids, proteins, etc.
Examples: hydrocarbons, proteins, enzymes, organic acids, fragrances etc.
C,H,O,N.S etc
By convention chemical compounds containing carbon are considered organic chemicals; but this definition is not entirely true.
Basalt, welcome
Cement, as with all substances, is entirely made of chemical compounds made of chemical elements. From the wording of your question it is not possible to give you a clearer answer as what you are asking is not clear.

Limestones are chemical sedimentary rocks, also called carbonate rock as it is made up of the carbonate radical CO3, hense Calcite CaCO3 Limestone. Although some limestones form by inorganic chemical precipitation most limestones are biochemical because they are mostly composed by organisms. Examples of limestone include Coquina composed almost entirely of fragmented seashells and Chalk, composed largely of microscopic shells.
Which ones?

Safety precautions for use with chemical compounds depend entirely on what particular compounds are being used, and how they are being stored and handled.

It is a compound, and compounds are types of homogeneous matter. Iodine crystals are composed entirely of I2 and as such are the same (homo) throughout (geneous).
Yes, for example, there's diamond which is composed entirely of the element carbon or sulfur which composed entirely of (yup... you guessed it) sulfur.

It is entirely composed of the element magnesium. Mg
An ionic compound.
A pure compound is made up entirely of one substance that has a single chemical property. A mixture is made up of two or more pure compounds with distinct chemical properties.
