Answer:
A) Parallelogram
Step-by-step explanation:
We can eliminate C right away, since it is general and encompasses all the other answers. The question asks us to be precise.
Now, we should plot the points on a graph and connect the points (from a to d). Doing this reveals a parallelogram with unequal sides and non-right angles. This eliminates answers B and D, respectively. Therefore the answer is A, a parallelogram.
