The correct answer is Teak. - Teak contains natural oils that make it resistant to decay and insect infection.

Sisham is the right answer.

Agree, sal is the correct answer.

Sal is the correct answer.

Teak is the right answer.

The right answer is teak wood.

Teak is the right answer.

Teak is not attacked by white ants and dry rot.

Overall sal is a better tree, and it's resistant to termites, fungi etc. Although teak is also resistant to white ants, sal overall has better resistance. That's why the answer is Sal here.

Teak is the Right answer.

White ant affects the lignin (tissue) part of the timber section due to which it assumes white color and hence, also called white rot.
Among all the given wood, teak is hardwood i.e. it has the strongest tissues and hence, offers maximum resistance against white ants or termites.

Note: Teak instead of resisting termites it actually kills the white ants.

Important Points:

Most timber is obtained from teak because it has the following properties:

1. Wood obtained from it is hard and strong and not resinous.
2. All woods contain oil (sapwood). Teak can retain these oils even after being felled and processed. Because of this, teak has greater weather-resistant properties.
3. Resistance against white ants.
4. It is durable and fire-resistant.
5. It does not allow the corrosion of iron fastenings.
6. Seasoning of teak wood is very easy and it is easily workable.
