What type of material is latex primarily used for in theatrical make-up?

Latex is primarily used in theatrical make-up for making skull cap molds and false noses because of its flexible and moldable properties. It can be shaped into various forms that are essential for creating realistic and dynamic character enhancements, such as prosthetics and masks. Theatre practitioners often use liquid latex to build up layers, allowing them to achieve detailed effects that can conform to the actor’s face or head, thus enhancing the overall portrayal of characters.

While latex has its utility in other areas of theatrical make-up, such as adding texture or being part of some waterproof effects, its most distinctive advantage lies in its ability to create detailed and lifelike prosthetics, like false noses and skull caps, making option B the most accurate answer.
