Critical Reasoning

Light plastic materials, such as bottles for freezing and containers for microwave cooking, have been shown by research to release carcinogenic toxins into the liquids and foods stored therein, thus posing a health risk problem for humans. Stainless steel is a better material health-wise for preserving food by freezing while only ceramics are healthy for heating foods and liquids in a microwave.

The statements above, if true, best support which of the following assertions?

A. We need to research plastics further to come up with an overarching rule regarding the viability of using plastics in freezing and cooking by microwave.
B. Plastic containers of any type should not be used to freeze liquids or to heat food in the microwave.
C. No significant positive health effects on human food consumption would result from banning plastics.
D. In very cold conditions, stainless steel releases less carcinogens than do light plastics.
E. Stainless steel is healthier for humans than plastics are.
