Contingency: what does "affects your person" mean?

[allenw]

I tried to sneak this into another thread, but no responses, so....

Contingency (text quoted below) is range "Personal," target "You," and the Contingent spell "must be one that affects your person." Does this mean:

A: It only works on spells that target a single individual, such as Shield or Invisibility;

B: It works on any spell for which the caster is a valid target, but even if the spell could ordinarilly target multiple targets (i.e., Haste(3.5), Teleport) it only targets the caster;

C: It works on any spell for which the caster is a valid target, and if the spell could ordinarilly target multiple targets (e.g., Haste(3.5), Teleport), the caster gets to decide who (if anyone) is targetted at the moment of activation ;

D: It works on any spell that could affect the caster, even if the caster isn't technically a "target" (e.g., Fireball), with area and effect spells "ground-zeroing" on the caster;

E: Other.

Thanks.

Contingency
Evocation
Level: Sor/Wiz 6
Components: V, S, M, F
Casting Time: At least 10 minutes; see text
Range: Personal
Target: You
Duration: One day/level (D) or until discharged
You can place another spell upon your person so that it comes into effect under some condition you dictate when casting contingency. The contingency spell and the companion spell are cast at the same time. The 10-minute casting time is the minimum total for both castings; if the companion spell has a casting time longer than 10 minutes, use that instead.
The spell to be brought into effect by the contingency must be one that affects your person and be of a spell level no higher than one-third your caster level (rounded down, maximum 6th level).
The conditions needed to bring the spell into effect must be clear, although they can be general. In all cases, the contingency immediately brings into effect the companion spell, the latter being “cast” instantaneously when the prescribed circumstances occur. If complicated or convoluted conditions are prescribed, the whole spell combination (contingency and the companion magic) may fail when called on. The companion spell occurs based solely on the stated conditions, regardless of whether you want it to.
You can use only one contingency spell at a time; if a second is cast, the first one (if still active) is dispelled.
Material Component: That of the companion spell, plus quicksilver and an eyelash of an ogre mage, rakshasa, or similar spell-using creature.
Focus: A statuette of you carved from elephant ivory and decorated with gems (worth at least 1,500 gp). You must carry the focus for the contingency to work.

The spell is cast at the same time as the contingency, which makes other targets beside yourself difficult. My group's criteria:

The spell must target you OR
The spell must be personal OR
The spell must affect an area and be centered on you

That means that Haste is ok, but it'll only target you. Shield is obviously fine. Fireball is also fine, but you'll be the centerpoint for it.
