Final answer:
The set that is not a subset of {1, 2, 3, 5} is {0}.
Step-by-step explanation:
To determine which set is not a subset of the set {1, 2, 3, 5}, we can compare each set to the given set. A subset is a set that contains all the elements of another set.
A. {1}: This set contains only the element 1, which is also present in the given set. Therefore, it is a subset.
B. {1, 3, 5}: This set contains the elements 1, 3, and 5, which are all present in the given set. Therefore, it is a subset.
C. No solution: This option implies that there is no set that is not a subset of the given set. However, we can see that set {0} is not a subset of the given set, as it contains an element (0) that is not present in the given set. Therefore, this option is not a subset.
D. {0}: This set contains only the element 0, which is not present in the given set. Therefore, it is not a subset.
Based on this analysis, the set that is not a subset of the given set {1, 2, 3, 5} is D. {0}.
