Magus arcana question

[Majakathi]

''The following magus arcana complement the hexcrafter archetype: arcane accuracy, broad study, familiar, and quicken magic.´''

What does this mean? Does it mean that magus archtype can only chose between those arcanas?

[Majakathi]

or does it mean you get those arcanas for free if u are that archtype

[Skylancer4]

Neither, they are arcanas that 'go well' with the archtype.
