As other commenters have noted,
between is standard for two items, and
among for three or more. The split between
among and
between looks like a great place to start, then, unless you're not quite sure how many items the sentence is talking about. I wasn't sure, so I started with parallelism.
The first
and seems merely to link
value and
workings, and that compound is just the object of a preposition in one item in the longer list of the things that must be balanced,
explanation..., revealing..., and to promote..... You could now eliminate answers that use between. (We should be careful that in some answers the list isn't somehow rejiggered to be just two items, each perhaps its own compound, but that doesn't turn out to be an issue here.)
So eliminate A, C, and E.
In B, the three parallel items are all gerunds,
explaining..., revealing..., and promoting.... That's perfectly fine.
In D, the three parallel items are the simple gerund
explaining, the noun
the revelation, and the infinitive
to promote. No two of those things are parallel, so eliminate D.
B it is.
