How many elements are in the set {5, 9, 12}?

  1. 1

  2. 2

  3. 3

  4. 4

The correct answer is: 3

This is because a set is a collection of unique elements and in the set {5, 9, 12} there are three unique elements, namely 5, 9 and 12. This means that there are three elements in the set and the answer is C. The other options are incorrect because A and B suggest that there is only one or two element in the set, while D is too high of a number for a set with only three elements.
