Hint: We know that plasticine is a putty-like modelling material made from calcium salts, petroleum jelly and aliphatic acids. Plasticine is used for children's play and as a modelling medium for more formal or permanent structures. Composed of calcium salts, petroleum jelly long-chain aliphatic acids (principally stearic acid, it is non-toxic, soft and malleable meaning it can both retain its shape and be reshaped again and again.

Complete step by step answer
We know that plastics are typically organic polymers of high molecular mass and often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, however, an array of variants is made from renewable materials such as polylactic acid from corn or cellulosic from cotton linters.
Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process. Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil.
Plastics are versatile, hygienic, lightweight, flexible and highly durable. It accounts for the largest usage of plastics worldwide and is used in numerous packaging applications including containers, bottles, drums, trays, boxes, cups and vending packaging, baby products and protection packaging.

Among the given materials plasticine is the most plastic material. So, the correct answer is option D.

Note: We know that standard modeling clay (like plasticine) cannot be baked. Polymer clay like the Fimo, Premo, and Sculpey brands in the craft store can be baked in a home oven according to the manufacturer's instructions. Standard modeling clay (like plasticine) cannot be baked. Plasticine is approximately 65% bulking agent (principally gypsum), 10% petroleum jelly, 5% lime, 10% lanolin and 10% stearic acid. It cannot be hardened by firing, melts when exposed to heat, and is flammable at higher temperatures.
