parallelagram
http://en.wikipedia.org/wiki/Parallelagram well specifically you would be a rectangle which has parallel sides like a square. a parallelogram can be a square or a rectangle because they all have parallel sides but only squares and rectangles have right angles on all sides. parallelograms have congruent sides which require acute and obtuse angles.
It's a rectangle.
the magnetic field around the adjacent pairs of wire
There are four wire pairs. White/Blue - Blue, White/Orange - Orange, White/Green - Green, and White/Brown - Brown. Only two pairs are used in Cat5 networks.
Twisted pairs
Twisted pair cabling has 4 pairs of wires (8 wires in total), but 10BASE-T and 100BASE-TX requires only 2 of those pairs (4 wires in total).Exams will often try to trick you by asking questions like 10baseT uses how many pairs so you think you're being asked how many pairs does it have? When really you're just being asked how many pairs does it use.

Either a square or a rectangle.

You are a rectangle! Note that it does not say all of your sides are of equal length.
The figure, as described, is impossible. If a quadrangle has 2 pairs of parallel sides then the number of right angles can be 0 or 4, but not 2.
