All prime numbers are defined as numbers greater than 1 that have no divisors other than 1 and themselves. To determine a group of numbers that includes all prime numbers, we should look for a set that comprises all positive integers greater than 1 while excluding composite numbers.
For instance, a group containing all natural numbers greater than 1 would include all prime numbers, since primes are a subset of natural numbers. On the other hand, any group that includes composite numbers would not meet the criteria since composites have additional divisors.
Therefore, the correct answer is a group that includes all natural numbers greater than 1, effectively encapsulating every possible prime number.
