Solution
The correct option is D It is a cross linked polymer
Bakelite is a thermosetting plastic possessing a permanent shape as well as size which cannot be altered on exposure to heat and pressure without decomposing it. Thermosetting Plastics are prepared via low molecular mass semi-fluid substances. On heating in a mould, these plastics get highly cross-linked leading to the formation of hard infusible and insoluble products. Bakelite is a condensation polymer made from formaldehyde and phenol as shown below:
