Answer :
I believe the best way for her to conserve petroleum would be to recycle the plastic products she uses. :)
Answer:
C) Recycle plastic products used
Explanation:
Making a list will not decrease the amount of plastics used therefore does not provide any type of conservation.
Removing plastics from her house does not provide any type of conservation
Flattening the plastic products before throwing them away doesn't provide any type of conservation
Recycled plastic is used to make more plastic products without the use of petroleum therefore conservation of petroleum.
