Answer :

Energy is a scalar quantity it doesn’t depend on an angle of projection; it depends only on the speed of projection, which is same for both cases.

It is given that height reached by the first particle is greater than that of second and we know that

Therefore θ_{1}> θ_{2}, Now for Time we know that it is directly proportional to Angle therefore, T_{1}>T_{2}.

For Range we can’t be sure as for complementary angle they can be equal also.
