Detailed Solution

Concept- A prime number is indeed a natural number greater than one that has only the factors 1 and itself.
According to the definition of prime numbers, prime numbers are greater than one.
Two follows one on the number line and is thus divisible by only one and itself, making it a prime number.
Three is just after two on the number line and is divisible only by one and itself, so we don't get a whole number when we divide 3 by 2. As a result, 3 is a prime number.
When we divide 5 by 2, we do not get a whole number; five is divisible only by one and itself; thus, 5 is a prime number.
When we divide 7 by any smaller number, we do not get a whole number, indicating that it is a prime number.
Because 11 is not divisible by any smaller number, it is a prime number.
The numbers 4, 6, 8, 9, and 10 are not prime because they can be expressed as the product of two smaller natural numbers.
As a result, the first five prime numbers are 2, 3, 5, 7, and 11.
Hence, the correct answer is option 3) 2, 3, 5, 7,11.
