Statistics — properties of the bivariate normal distribution

Let (X,Y)∼BVN(μ1,μ2,σ12,σ22,ρ)(X,Y)\sim\mathrm{BVN}(\mu_1,\mu_2,\sigma_1^2,\sigma_2^2,\rho). If σ12=2\sigma_1^2=2, σ22=3\sigma_2^2=3 and ρ=0\rho=0, then consider the following:

I. E(X)=E(Y)E(X)=E(Y)

II. E(XY)=2E(XY)=2

III. XX and YY are independent

Which of the above is/are correct?
