Sagot :

Answer:

The ameliorated retort, pertaining to the presented and contemporaneous interrogate is acknowledged as B.  

Explanation:

To convey such rhetoric, the following is obligated for comprehension:

- To commence, according to Wikipedia, a "Pure Substance" is defined as: "A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds."

- In addition, invariantly according to Wikipedia, a "Chemical Mixture" is defined as: "In chemistry, a mixture is a material made up of two or more different substances which are not chemically combined. A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids."

Hence, veracious retorts are subject to commence.

Given peculiar substances,

H20, an optical isomer is in recognition as a pure substance.

Likewise, CO2, an enantiomer is in the congruence of a pure substance.

Hence, methyl anthranilate acquiring a chemical formula of C8H9NO2, acknowledged as grape flavoring, is a mixture.

Invariantly, the diasteromer epimer, procuring a chemical formula configuration of C12H22O11, sucrose, is acknowledged as a mixture.

Hence, ideologically, the retort in the congruence of veracious philosophy is B. "The pure substances are carbon dioxide and water; mixtures are sugar and grape flavoring."
