A prime number is defined as a natural number which is only and only divisible by 1 and itself.
Note that 72 and 106 are even numbers, so they will have at least one factor as 2, which is neither 1 nor the number itself. Therefore, 72 and 196 cannot be a prime number.
Now, consider that 141 has the sum of digits as 6 which is divisible by 3, so according to the divisible rule of 3, the number 141 is divisible by 3, which is neither 1 nor the number itself. Therefore, 141 cannot be a prime number.
The last choice 107 do not possess any factor other than 1 and 107, so the number 107 is referred as a prime number.
Thus, option D is the correct choice.
