For odd function f(x) = -f(-x)
for option A :Â f(x) = $$2^{-x.x}$$, f(-x) =Â $$2^{-(-x).(-x)}$$ =Â $$2^{-x.x}$$ = f(x). Hence Option A is not correct
for Option B : f(x) = $$2^{x-x.x.x.x}$$, f(-x) =Â $$2^{(-x)-(-x).(-x).(-x).(-x)}$$ =Â $$2^{(-x)-x.x.x.x)}$$Â $$\ne\ -f\left(-x\right)$$
Neither A or B are correct
