What is the milky exudate from certain plants that coagulates on exposure to air?

Latex
Larva
Legume
Lever

The correct answer is: Latex

The milky exudate from certain plants that coagulates upon exposure to air is known as latex. Latex is a natural product produced in the sap of various plants, particularly in certain types of trees and shrubs such as rubber trees. When the latex is exposed to the air, it begins to thicken and coagulate, creating a solid form as the moisture evaporates and it interacts with the oxygen in the air. This property allows latex to be collected and used in various applications, including the manufacturing of rubber products. The other terms listed do not fit this description. Larva refers to a developmental stage in an insect's life cycle, legumes are a type of plant, often producing pods, and lever is a simple machine or tool. Thus, latex is the most appropriate choice for the milky exudate that coagulates when it encounters air.
