Which of the following is true about Kotlin?

Kotlin being a statically typed programming language means that the type of every variable is known at compile time. This characteristic allows for better optimization during the compilation process and helps in catching type errors early before the code is executed, improving reliability and readability. Statically typed languages enforce strict type rules, which can help developers avoid common errors associated with dynamic typing.

The option regarding Kotlin running only on iOS devices is inaccurate since Kotlin was primarily designed for JVM and Android development, though Kotlin Multiplatform does allow shared code for other platforms, including iOS, but it does not run solely on iOS. The statement about requiring a web browser to run is also incorrect; Kotlin is typically compiled to run on a JVM or in an Android environment, and does not necessitate a web browser. Lastly, Kotlin indeed supports object-oriented programming, allowing developers to create classes, objects, and interfaces, aligning it with OOP principles like inheritance and encapsulation. Thus, the assertion about Kotlin not supporting object-oriented programming is not true.
