The correct choice is (d) Solid phase pressure forming

The best I can explain: SPPF in thermoforming stands for solid phase pressure forming. The SPPF process is primarily used to thermoform PP, a crystalline polymer that is difficult to thermoform uniformly in melt phase machines due to the sharp decrease in melt strength (viscosity) at its melting point.
