Factorize:

5040
= 2^4X3^2X5X7
=7x8x9x10

A: If d is a prime, only possible value is 7. - Sufficient.
B: a>b>c>d => d = 7 - Sufficient

Am I missing something ?

(1) d is prime
(2) a>b>c>d


Question says,

abcd =5040
thus
a,b,c and d could be 7,8,9 and 10 or -7, -8, -9, -10 because

7*8*9*10 = 5040
and also
(-7)*(-8)*(-9)*(-10)=5040

Statement 1: d is prime. Clearly d is 7, as prime can not be negative. Sufficient

Statement 2: a>b>c>d => d could be 7 or -10. Not sufficient.

Hence ans A it is.

Yes thats the mean little trick there. You will have to consider the negative numbers too. :)
