Option D is right.

Glued sheets are loaded into a multiple-opening hot press. presses can handle 20-40 sheets at a time, with each sheet loaded in a separate slot.

When all the sheets are loaded, the press squeezes them together under a pressure of about 110-200 psi (7.6-13.8 bar), while at the same time heating them to a temperature of about 230-315° F (109.9-157.2° C).
