A well seasoned timber may contain moisture up to A. 4 to 6% B. 6 to 8% C. 8 to 10% D. 10 to 12%

The correct answer is A. 4 to 6%.

A well seasoned timber may contain moisture up to 4 to 6%. This is because the wood has been dried to a point

where it is no longer susceptible to decay or warping. The moisture content of wood can vary depending on the type of wood, the climate it is grown in, and the way it is harvested and processed. However, for most types of wood, a moisture content of 4 to 6% is considered to be ideal.

Option B, 6 to 8%, is too high. Wood with a moisture content of 6 to 8% is more likely to decay or warp. Option C, 8 to 10%, is also too high. Wood with a moisture content of 8 to 10% is even more likely to decay or warp. Option D, 10 to

12%, is much too high. Wood with a moisture content of 10 to 12% is very likely to decay or warp.

In conclusion, the correct answer is A. 4 to 6%.
