If a and b have diff coordinates then it may be more than 90 degrees or less than 90 degrees. So 1st option is ruled out.

If angle b is twice is of angle c then also you can't be sure of more than 90 degrees.

Combining two options will not give any more info. So E is the answer

In what case would the angle be greater than 90 degrees?? I mean what should be the values of the co ordinates for it to be greater than 90 degree, Also what should the co-ordinates be for the angle formed to be 90 degrees??
