Plywood is made of three or more thin layers of wood bonded together with an adhesive. Each layer of wood, or ply, is usually oriented with its grain running at right angles to the adjacent layer in order to reduce the shrinkage and improve the strength of the finished piece. Most plywood is pressed into large, flat sheets used in building construction. Other plywood pieces may be formed into simple or compound curves for use in furniture, boats, and aircraft.

So answer is correct.

Running at the right angles.

I think it is parallel.

At right angle.

Adjacent veneers should be parallel. But I am in confusion about grains of adjacent veneers. Please, anyone make it clear.

Yes, B is correct.

Grains of adjacent veneers should be parallel to each other. Grains of veneers placed one below the other should be perpendicular.

B is the correct answer.

Yes, I agree with answer because veneers in odd numbers are placed one above the other with the direction of grains of successive layers at right angles to each other.

Thank you so much @Mutun Rohidas.
