Electricity & Magnetic Fields - What do they Resemble?

[stickplot]

When electricity flows through a coil of wire, what does the resultant magnetic field resemble?

a the magnetic field of a bar magnet
b the magnetic field of a horseshoe magnet
c the magnetic field around a straight wire
d the magnetic field around a circular magnetic disc.

ok so i know that it creates a circular like magnetic field like that of a bar magnet, but I am not sure if it acts like a bar magnet also having north and south poles which attract and repel, and c doesn't really give me much to think on, so I am not sure whether it would be a, b, or d.

The question just asks what the field resembles and not what it acts like. You know it resembles that of a bar magnet.
