In every answer choice, it is not immediately clear whether his passion serves to refer to the entrepreneur or to the partner.
I would ignore this SC.

Mitch
Considering "HIS" is causing irrelevance,would replacing HIS with "A" make better sense?

Toward the end of that year, the food and beverage entrepreneur was looking for a partner - someone not only who could provide expertise in developing talent pipelines, but sharing A passion as well to launch a new product on the market.

A) someone not only who could provide expertise in developing talent pipelines, but sharing a passion as well to launch
B) someone who not only could provide expertise in developing talent pipelines, but also shared a passion to launch
C) someone who not only could provide expertise in developing talent pipelines, but also share a passion to launch
D) that being someone who not only could provide expertise in developing talent pipelines, but sharing a passion for launching
E) being someone who not only could provide expertise in developing talent pipelines, but share a passion as well, launching

Now, would the answer be "C"?

A- Not only is incorrectly used
B- "share" verb is not parallel
D/E - not only - but also (not-idiomatic)

Your reasons for eliminating A, B, D and E are valid.
The OA is C, but this option lacks parallelism.

MODAL VERBS include can, could, would, should, etc.
The BARE INFINITIVE is to + VERB with the to omitted.
A common verb structure is MODAL VERB + BARE INFINITIVE:
John could win the game.
Here, could is a modal verb, while win is the bare infinitive of to win.

Rule:
not only X but also Y must serve to connect PARALLEL FORMS.

C: someone who not only COULD provide but also SHARE
Here, could (modal verb) and share (the bare infinitive of to share) are not parallel forms.
Eliminate C.

The SC above does not have a viable answer choice.

C, corrected: someone who could not only PROVIDE but also SHARE
Here, provide (the bare infinitive form of to provide) and share (the bare infinitive form of to share) are parallel forms.

Excellent, thank you very much for the precise explanation Mitch.

sksk,
can you tell the source of this SC, so that we be skeptical about it from now onwards
Thx
