B.DBP
C. Cresyl phosphate
D. Sodium adipate

Answer 1

Hint :A plasticizer (UK: plasticiser) is a compound that is applied to a material to make it softer and more flexible, increase its plasticity, reduce viscosity, or reduce friction during manufacturing.

Complete Step By Step Answer:
Plasticizers are routinely added to polymers like plastics and rubber, either to make the raw material easier to handle during fabrication or to fulfil the needs of the end product's use. Plasticizers are often used to soften and flexible polyvinyl chloride (PVC), which is otherwise hard and brittle, making it ideal for items such as vinyl flooring, garments, bags, hoses, and electric wire coatings.
Plasticizers are frequently used in concrete formulas to make them more workable and fluid for pouring, reducing the amount of water required. Prior to moulding and shaping, they are frequently added to clays, stucco, solid rocket fuel, and other pastes. Plasticizers and dispersants have a lot of overlap in these applications.
Now, coming to the question;
Plasticizers (UK: plasticisers) and dispersants are additions that make a material more plastic or fluid. Plastics, particularly polyvinyl chloride, are the most common applications (PVC).
When plasticizers are used with other materials, such as concrete, clays, and related items, the qualities of such materials are improved as well.
DOP (Dioctyl phthalate) is a chemical that is found in flooring, carpets, notebook covers, and powerful explosives like Semtex.
DBP (Di-n-butyl phthalate) is a chemical that is used in cellulose plastics, food wrappers, adhesives, fragrances, and cosmetics.
Hence, the correct options are: (A) DOP, (B) DBP and (C) Cresyl phosphate.

Note :
Esters of polycarboxylic acids with linear or branched aliphatic alcohols of intermediate chain length are commonly employed as plasticizers in PVC and other polymers. Low toxicity, compatibility with the host material, non-volatility, and cost are among the criteria used to choose these chemicals.
