The last line of a proof represents:

          The conclusion.

We know that a proof is a mathematical demonstration of a statement or a evidence that is necessarily true.

While proving a statement we start by taking a given statement  and with the help of some other theorems or axioms we proceed further to prove our argument.

At the last the result that is obtained or the last line is the conclusion of the proof.

it is probably the graph on the bottom right.

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
