The prime number definition: the numbers which is divisible 1 and itself. or the number contains only 2 factors are prime numbers.
A.31 = 1,31 only 2 factors so it is a prime number.
B.61 = 1,61
C.71 = 1,71
D.91 = 1,7,13,91 In this option D there are more than 2 factors.
And 91 divisible 7 which is 13.
91/7= 13,
so, option D is the correct answer.
A.31 = 1,31 only 2 factors so it is a prime number.
B.61 = 1,61
C.71 = 1,71
D.91 = 1,7,13,91 In this option D there are more than 2 factors.
And 91 divisible 7 which is 13.
