should be E
We need to find if y>1.5 z
first statement says y>0.66 Z , clearly insufficient because if y >0.66 z it can or cannot be greater than 1.5 z
2nd statement says y<2z, again insufficient because if y <2z it can or cannot be greater than 1.5 z
combined 0.66z<y<2z
again y can be greater than or less than 1.5 z , possible values of y are
1.2 z(<1.5z), 1.7z(>1.5z)

By mistake I understood in a wrong way.
