Which function is needed to print output in Kotlin?

• A. log()
• B. write()
• C. display()
• D. print() or println()

Answer: (D)

In Kotlin, the functions used to output text to the console are `print()` and `println()`. The `print()` function prints the specified message to the console without adding a newline at the end, while `println()` outputs the message followed by a newline. This is fundamental for displaying information in Kotlin applications, making it the most appropriate choice for outputting data. The other options do not correspond to standard functions in Kotlin for outputting text to the console. Functions like `log()` or `write()` may be used in different contexts or libraries, but they are not part of the Kotlin standard library for console output. Similarly, `display()` is not a recognized function in Kotlin for this purpose.
