Runnable in java

hi,
I have doubt in the following multiple choice question.

Runnable  is
A)Exception handling
B)Method
C)Interface
D)Class

Which one is correct option A or option B or option C or option D?  

What do you think, and why? See java.lang.Runnable for more information on this.

@Tim Moores,
I think option A and option C are correct.
Is it right or wrong?

Runnable is Exception handling?Is it right

Anyone please reply soon

This the JavaDoc for Runnable:
https://docs.oracle.com/javase/8/docs/api/java/lang/Runnable.html

That should you answer that question.

Runnable is Exception handling?Is it right

No. It has to do with concurrency. As to B, C or D, both Dave and I pointed you to the javadocs which answers that.

Runnable represent a task in Java which is executed by Thread. java.lang.Runnable is an interface and defines only one method called run(). When a Thread is started in Java by using Thread.start() method it calls run() method of Runnable task which was passed to Thread during creation.
