Cement
Paste
Oil
Glue
Answer is Right!
Answer is Wrong!
The odd one out is oil. The other three are all adhesives, while oil is a lubricant.
Adhesives are substances that are used to stick two or more things together. They work by forming a strong bond between the surfaces of the materials being joined. Paste, cement, and glue are all adhesives.
Lubricants are substances that are used to reduce friction between two surfaces. They do this by forming a thin film between the surfaces, which prevents them from coming into direct contact. Oil is a lubricant.
Therefore, oil is the odd one out in the given set of options.
