Final answer:
Set A, defined as y , is an Empty Set because it contains no natural numbers less than 1.
Step-by-step explanation:
The question is asking to identify the type of set given by the notation A = y . The notation describes a set of elements (y) that are natural numbers (N) and that are also less than 1. Since there are no natural numbers less than 1 (remember that natural numbers start from 1 and go upwards), the set A does not contain any elements. Therefore, A is an Empty Set.
