A. I only

Explanation :

f(x) = x^2 -3

Let x=0 then f(x) = -3
X= 1 then f(x) = -2

So least value of f(x) is -3 when X is a integer.

f(x) will not become 0 at any value for x to be a integer.

f (x) = x² - 3

f(x)=6,

x² - 3=6,

x²=9,x=+3 or -3

Possible.

f(x)=6,

x² - 3=0,

x²=3,x=sqrt(3)

x is not an integer,Not possible

f(x)=-6,

x² - 3=-6,

x²=-3,square of integer cannot be -ve

Pick A
