The correct answer is (d) Plywood

To explain I would say: Under normal conditions, the plywood formwork can be used for 20 times to 25 times and the timber formwork can be used for 10 times to 12 times. The plywood formwork give surface which are plain and smooth and they may not required any further finishing treatment.
