Reno:

My option depends actually on the person who needed my help if it were Rude or President Rufus i would help them withought a second thought...but
Should it be someone else this is what i would do:

First i would cast Pyramid to trap the person in danger my pyramid serves not only to stop any person from making a move but also serves as a sort of a barrier the guy who was stuck would fall down on the ground but probably wouldnīt die since my pyramid protected him/her from the shock.

Using my incredible agility (that you see in FFVII AC) i would quickly climb to the top and secure the treasure then i would slowly climb down while whistling.

When i got down into the ground i would ask "Hey man you alright" with an ironic look.

And finally walked away sharing the treasure with Rude.

So in resume my opinion would be d) a slight variation.
