The answer is C. Oil.
Cement, paste, and glue are all adhesives, while oil is not. Adhesives are substances that are used to stick two or more things together. Cement is a powder that is mixed with water to form a paste. Paste is a thick, sticky substance that is made by mixing flour or starch with water. Glue is a sticky substance that is made from natural or synthetic materials. Oil is a liquid that is made from petroleum or plants.
Cement, paste, and glue are all used to stick things together. Cement is used to build structures, such as buildings and bridges. Paste is used to stick paper and other materials together. Glue is used to stick a variety of materials together, such as wood, paper, and fabric.
Oil is not used to stick things together. It is used for a variety of other purposes, such as cooking, lubricating machines, and making cosmetics.
