Which among the following is not product of plants?

The correct answer is Option (4) –Honey

Honey is not produced by plants themselves but by honey bees. Bees collect nectar from flowers, which is a sugary fluid produced by various plants, and then transform it into honey through a process of regurgitation and enzymatic activity. While honey originates from plant nectar, it undergoes significant processing by bees before it becomes the final product.

The other options:

• Cereal: Cereal grains such as wheat, rice, maize, and oats are produced by various grass species.
• Rubber: Rubber is produced from the latex sap of certain plants, such as the rubber tree (Hevea brasiliensis).
• Timber: Timber refers to wood harvested from trees, which are plants.

So, all the other options are products directly or indirectly produced by plants.
