Which option is correct about E₂ = {x : x is a month name}?
Answer and explanation
Correct answer: It is a finite set with 12 elements
The set consists of the names of the twelve months in a year: January through December. Its membership is clearly defined, and no additional month names are possible in the ordinary calendar-year context. Because it has exactly 12 members, it is finite, not infinite, empty, or a singleton. Therefore, option B is correct.
