Answer
The polymer chain consists of repeating units characterized by the presence of carbon-fluorine bonds. The structure shows various substituents, particularly CF3 groups, which indicate the fluorinated nature of the monomers.
Step 2

Answer
Next, we will evaluate each option:
A. CH2=CF2 and CF2=CFCF3:
The presence of CF3 suggests the possibility of this pair.
B. CF2=CF2 and CH2=CFCF3:
This option has repeating CF2, which does not align with the CF3 characteristics.
C. CH2=CF2 and CH2=CF3:
This has CH2 and does not correlate with CF3.
D. CF2=CF2 and CH2=CFCF3:
Similar to option B, it does not represent the CF3 structure well.
Step 3

Answer
After matching the characteristics of the polymer backbone to the monomer options, the correct answer is A. CH2=CF2 and CF2=CFCF3 since it fits the structure and nature of the repeating units observed in the polymer.
