b the explosion of fireworks is an example of a physical reaction.
c chopping a big block of cheese into pieces is an example of a chemical reaction.
d chopping a big block of cheese into pieces creates light.

Explanation:

Question 1

The question is about categorical ways of thinking about matter. Physical and chemical are fundamental categorical ways to analyze matter (physical properties/changes vs chemical properties/changes), while solid/liquid are states, natural/unnatural and beneficial/harmful are not standard scientific categorizations for matter.

To find what is compared with physical properties of matter, we analyze options. Chemical properties are the logical counterpart to physical properties when comparing/contrasting, while a painting, Periodic Table (as a list, not a property comparison), or basketball appearance (a physical property example, not a contrast) don't fit.

The info says producing sound/light means likely chemical reaction, and fireworks explosion does that. So it's a chemical reaction example. Option B is wrong (physical), C is chopping (physical change), D is false (chopping doesn't create light).

Answer:

C. physical and chemical
