Answer:

Step-by-step explanation:

We need more than one solution , it means we should have more than one set of (x,y,z) values

Now looking at options

since 13 is prime number , 13=13x1x1 which gives only one solution and this even wont fit in xyz=72

So this can be ruled out

We are given with xyz=72=2^3x3^2

So for making 15 out of the factors we only have choice (9,4,2)

similary it can be checked for 16

for 14=2x7

we have (8,3,3) : 8+3+3=15

and (6,4,3) ;  6+4+3=15

so for S=14 we have more than one solution
