Answer: C. 211
Explanation
• Prime number: any integer different from 0 or ±1 that is not divisible without a reminder by any other integer besides ±1 and itself.
If we choose 201, we can see that it is divisible over 3 (if the sum of the numbers adds to 3, then it is divisible, 2 + 0 + 1 = 3) as:
[tex]\frac{201}{3}=67[/tex]
Then, it is also divisible by 67 and 1. Thus, this is not a prime number.
Also, if we choose 205, it ends in 5, meaning that it is divisible over 5:
[tex]\frac{205}{5}=41[/tex]
Then it is also divisible by 41 and 5.
Finally, if we choose 211 is not divisible by, 2, 3, 4, 5, 6 nor 7, etc... Then, this the prime number.
