Hint: To answer this question, you must recall the properties that discuss only the physicality of the sucrose molecules. Chemical changes in the sucrose molecules will represent the chemical properties. Changes that are reversible and change only the physical appearance are known as physical changes. Chemical changes are usually irreversible changes.
Complete step by step answer:
We know that there are two types of changes that generally occur in matter, namely physical changes and chemical changes.
Physical changes are the changes that take place when a substance is boiled, melted, condensed or precipitated and only the physical properties of the substance are affected. Chemical changes generally involve chemical reactions.
Using the definitions above, we can now classify the given options as chemical changes, or chemical properties, and physical properties.
Option A tells us that sucrose is a white crystalline solid. It gives us information about the physical appearance of sucrose molecules and is thus a physical property.
Option B refers to the constituent elements that make up the sucrose molecule. It gives us information about the chemical formation of the molecule and is thus a chemical property.
Option C, D and E all refer to various chemical reactions of the sucrose molecules thus, discussing the chemical properties of sucrose.
Hence, the correct option is A.
Note:
Sucrose is obtained from cane sugar and sugar beets. It is found in all photosynthetic plants. Sucrose is a non-reducing sugar and is formed by condensation of one molecule of glucose and one molecule of sucrose. Sucrose is a colorless, odorless crystalline compound with melting point of around ${185^{\text{o}}}{\text{C}}$ . It is dextro-rotatory but does not show mutarotation.
