CAT 2003 retest...Quant Query

[anandv]

For qn no 98 in the cat retest paper given in bulletin

If a,a+2,a+4 are prime nos,then no of possible solutions for a is-

The key suggests the answer is 2

but in my opinion ,it shud be 1

-3,5,7 is the only pair...and no other pairs are possible
-1,3,5 is not a pair...since the number 1 is neither prime nor composite

so can someone enlighten if I have done some mistake??

[cat_dude]

[jumbo1511]
