(3) thrown with an angle theta , angle has to be positive i guess. so when thrown with an angle theta from the ground the slope will increase ( for some time) but then because of the gravity the particle slope will decrease and finally will be 0 or dormant/static when the body hits the ground.

well the correct answer is 1.but how
hmm part 1 why's that. an answer does need to have a logic. ( even if it is wrong logic, it doesn't matter) . in 1st option the slope m decreases constantly with time. Such graph is possible when you hold a particle and simply drop it. like dropping a ball from top of building ( not throwing it) , which makes it fall directly at an angle of 90 degree, hence deceeasing the slope constantly with time, and finally to 0 at some time t, when particle hits ground.
