Its basically asking if k is prime or not. If k were prime then 1 and k would be the only factors and there would be no p a factor of k such that
1<p<k

Stmt I

k>4!
4!=24

If k=25 the answer is yes
If k = 29 the answer is no

INSUFF

Stmt II

13!+2<=k<=13!+13

Any number between 13!+2 and 13!+13 will always be non prime i.e they will have factors from 2-13 (write out 13! = 13*12*11*10*9*8*7*6*5*4*3*2*1 )

Once a number is divisible by 2,3,4...if u keep adding 2 or 3 or 4... it will always be divisible by it again

This tell us k is non prime and 1<p<k exists

Hope this helps! Let me know if u still have questions
