Of the sets desctibed, which is the uniwersa selle

all real numbers

all integers

prime numbers

even numbers

number three

Step-by-step explanation:

Even numbers are those which are divisible by 2

Prime numbers are the numbers which are divisible by 1 and the number itself

Since, we have to take only positive numbers

Carrie has taken out the set of even number within the set of prime number

So, 2 is the only number inside this set because 2 is even as well as prime

Hence, universal set will be prime numbers

Therefore, Option 3 is correct that is prime numbers.
