Pams...whaddya think of my analysis...because if we count the way you are counting, then the question should read:

for what integer values of x is 25-x^2 an integer that has a defined whole number as square root:

In this case also, the answer is 4 --> -4,-3,3,4

Well...the question was wrong then...because hydrogen is the most abundant element in the universe (including the earth!!) but it does not exist in free form (it combines easily with other elements). However, the question imposed no restrictions on elements combining with other elments Cry I am sorry that their questions are always incomplete...

i think its blood poisoning-Septicaemia is caused when certain bacteria get into the bloodstream. Without prompt medical treatment, septicaemia can be fatal.

5
6
7
3

Well, then you have to include 5, -5 and 0 (if we take your approach) because of the way the stupid question is worded!! In that case the answer will be:
-5,-4,-3,-2,-1,0,1,2,3,4,5 => 11 (not an option).

If you consider only positive integers than the answer will be 6...this is messed up...because they are not defining positive or negative integers so the correct answer would be "infinity"
