A. $h_{11} = 0, h_{12} = 0, h_{21} = \text{very high and } h_{22} = 0$
B. $h_{11} = \text{very high}, h_{12} = 0, h_{21} = \text{very high and } h_{22} = 0$
C. $h_{11} = 0, h_{12} = \text{very high}, h_{21} = \text{very high and } h_{22} = 0$
D. $h_{11} = 0, h_{12} = 0, h_{21} = \text{very high and } h_{22} = \text{very high}$
