Smita wants to find new ways to recycle materials. which field of study would be most useful to her? a. meteorology b. chemistry c. microbiology d. zoology

Option B

Explanation:

The chemical properties of a material play a very important role in recycling and reusing any thing.

For instance - if a plastic on melting transforms into a form which cannot be re-converted into its original form, then such plastics are not reusable materials

A recyclable material must be able to regain its original molecular structure and size though physical processes such as heating, melting, remolding etc.

hence, option B is correct  

true is the answer : )
