Q 308

An 8th level psion with 13 dex manifests Crystal Shard. Assuming they have no feats or items to boost their to-hit, their rolls is 1d20 + 4 [BAB] + 1 [Dex].

However, if this Psion has a Psicrystal, they can use the 'Deliver Touch Power (su)' ability of the psycrystal to have their psicrystal deliver the attack for them. Because they use the medium BAB track instead of the poor track, a level 8 psicrystal with one of it's level-up stat increases placed into dex will roll the attack as 1d20 + 6 [BAB] + 4 [Size] +3 Dex].

Is this correct? Or....

A. Psicrystals use their owners BAB
B. Psicrystals cannot improve their dex bonus as they do not normally have the stat, the self propulsion ability grants them one temporarily.
C. Deliver Touch Power only effects melee touch attacks, not ranged touch attacks
