Question

Assertion : Teflon has high thermal stability and chemical inertness.
Reason : Teflon is a thermoplastic.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false
