The Correct Option is A

Approach Solution - 1

Teflon is polytetrafluoro ethylene and it is prepared from tatrafluoro ethylene by heating under pressure in the presence of ammonium peroxydisulphate. $n CF _{2}= CF _{2} \frac{\left( NH _{4}\right)_{2} S _{2} O _{8}}{\text { high pressure }}\left( CF _{2}- CF _{2}\right)_{n}$ It is chemically inert and heat resistant polymer:

Approach Solution -2

Tetrafluoroethylene (nCF2=CF2) may be polymerized to create Teflon.Polymerisation[−CF2−CF2−]n
When relatively tiny molecules called monomers unite chemically to form long chains like a network molecule called a polymer, the process is known as polymerization. Tetrafluoroethylene is the monomer unit employed in this instance.
Teflon is a hydrophobic fluorocarbon solid with a high molecular weight compound made of fluorine and carbon.
One of the lowest coefficients of friction of any substance is found in Teflon.
It is not reactive because of the strength of the carbon-fluorine link and because it cannot be used in pipes and containers for corrosive substances.
Its primary uses in industry are brushes, sliding plates, seals, gears, and simple bearings. Teflon is therefore made of polytetrafluoroethylene, a fluorocarbon that is non-reactive due to the strength of its C–F bonds.
Since Teflon, a substance resistant to heat, is coated in black on non-stick frying pans, Option A is the best choice. A tetrafluoroethylene polymer is teflon.

Types of Polymerization Reactions

Polymerization is a chemical reaction in which a large number of monomer molecules combine to produce a polymer. A polymerization can yield macromolecules with a linear or branching structure. They can also take the form of a three-dimensional complicated network. 

Types of Polymerisation

Polymerization reactions are divided into two groups, namely, Addition polymerization (chain reaction) and condensation reaction (step reaction). 

  • Addition Polymerisation: As the name denotes, we can see the addition of monomers to form a polymer, twice the number or even more than that. Here, we can either select monomers of the same species or of different species. When we choose the single species monomers for the polymerization, the product thus formed is known as homopolymer (for example polythene used to make bags). When we use two different species for additional polymerization, the polymer would be known as copolymer (for example, Buna-S and Buna-N).
  • Condensation Polymerisation: In the condensation polymerisation, we can find elimination of compounds like HCL, water, alcohol etc...; while the monomers condense during the reaction process. This reaction happens between tri-function and bi-function monomer units and results in the formation of polymers like nylon.
