Answer
In a polymerisation reaction where water is released, it is likely a condensation polymerisation. This type of reaction typically involves the formation of a polymer through the elimination of small molecules, such as water.

Answer
The options given are Ethene, Glucose, Styrene, and Vinyl chloride.
Ethene: This is an alkene and forms polymers via addition polymerisation, not releasing water.
Glucose: A sugar that can participate in condensation reactions but does not typically form polymers in this manner.
Styrene: An aromatic hydrocarbon, more likely to undergo addition polymerisation.
Vinyl chloride: Similar to ethene, this will also undergo addition polymerisation and not release water.

Answer
The most likely monomer involved that releases water during polymerisation is Glucose (B), as it can participate in condensation reactions forming glycosidic bonds, releasing water in the process.
