• A. Drying
• B. Conditioning
• C. Seasoning
• D. Treatment

Answer: (C)

Seasoning is the term used for the controlled, commercial drying of timber to lower its moisture content. This process is done in a deliberate, often kiln-based or air-drying method, with the goal of stabilizing the wood so it shrinks and warps less when used. It’s a specific type of drying that targets a suitable moisture level for wood products, typically much lower than in freshly cut timber.

Drying is a broader idea of removing moisture and can refer to any method or setting, not necessarily in a commercial context or with controlled timing. Conditioning relates to adjusting or redistributing moisture after drying to even out moisture across the piece, sometimes as a follow-up step. Treatment means applying protective chemicals or finishes to the wood. So the definition matches seasoning precisely.
