Turpentine is extracted from the wood (xylem) of Pinus (Gymnosperm).

1. Turpentine is a fluid obtained by the complex distillation of resin obtained from trees, mainly various species of pine (Pinus). It is composed of terpenes, mainly the monoterpenes, alpha-pinene and beta-pinene.
2. Turpentine oil is obtained by boiling resin at 155 degrees Celsius in large tubs. It has a potent odour that is similar to that of nail polish remover.
3. Turpentine is extracted from the leaves of Pinus.
4. Turpentine is a by-product of photosynthesis in Pinus.

Correct answer: Turpentine is a fluid obtained by the complex distillation of resin obtained from trees, mainly various species of pine (Pinus). It is composed of terpenes, mainly the monoterpenes, alpha-pinene and beta-pinene.

Solution

The correct choice matches the known source and composition of turpentine: it is produced by distilling resin from pine trees, especially Pinus species. Its main components are terpene hydrocarbons such as alpha-pinene and beta-pinene.
