A) a constant function.....

Answer 2

Answer:

19. A) CONSTANT FUNCTION

Step-by-step explanation:

Singleton set can be defined as the set that contains onlyone element.

In a constant function, all the domains are mapped to a common co-domain. If we make a set of range, we will get only one element, i.e, singleton set.

So, obviously the answer is Constant function
