D. None of the above

Answer

To determine which plastic is obtained from CHCl₃ (chloroform) through the given reactions, we can break down the process step by step.

### Step 1: Reaction of CHCl₃ with HF and SbF₃
- **Starting Material**: Chloroform (CHCl₃)
- **Reagents**: Hydrogen fluoride (HF) and antimony trifluoride (SbF₃)
- **Process**: When CHCl₃ reacts with HF and SbF₃, two chlorine atoms are replaced by fluorine atoms.
- **Product X**: The resulting compound is CHF₂Cl (chlorodifluoromethane).

### Step 2: Heating at 800°C
- **Starting Material**: CHF₂Cl
- **Process**: When CHF₂Cl is heated at 800°C, it undergoes a reaction where two molecules of CHF₂Cl are involved.
- **Product Y**: This heating leads to the formation of tetrafluoroethylene (CF₂=CF₂).

### Step 3: Polymerization of Tetrafluoroethylene
- **Starting Material**: Tetrafluoroethylene (CF₂=CF₂)
- **Process**: The tetrafluoroethylene undergoes polymerization, which is the process of converting simple molecules into a polymer.
- **Final Product**: The polymer formed is polytetrafluoroethylene (PTFE), commonly known as Teflon.

### Conclusion
The plastic obtained from the reaction of CHCl₃ as described is **Teflon (PTFE)**.

### Summary of Steps:
1. CHCl₃ + HF + SbF₃ → CHF₂Cl (Product X)
2. CHF₂Cl (at 800°C) → CF₂=CF₂ (Product Y)
3. CF₂=CF₂ → Teflon (PTFE) (Polymerization)

### Final Answer:
The plastic obtained from CHCl₃ is **Teflon**.
