Yes, the incorrect statement is:
C. Plastics are ductile.
Here's why:
Ductility is the ability of a material to be drawn into wires. Plastics, in general, are not known for their ductility. They are more likely to break or fracture than be drawn into wires.
Plastics are well known for being chemical resistant, durable, and excellent electrical insulators.

The incorrect statement is "Plastics are chemical resistant".
Plastics are generally resistant to some chemicals, but they are not resistant to all chemicals.
For example, plastics can be dissolved by certain solvents, and they can also be corroded by certain acids and bases.
The other statements about plastics are all correct. Plastics are durable, ductile, and excellent electric insulators.

Question is asking incorrect statement. So all option are correct except option A. So correct answer should be A.

Plastics are Ductile, Durable and also Good Insulators but less resistant to chemicals, so option A is correct.

Yeah, plastics can be converted to the wire. So ductility is possible.
But, also plastic is a good insulator. So both are correct.
But, also plastic is a good insulator. So both are correct.
