As well as a conduit for the vital distribution of oxygen and hydrogen molecules across the planet, the Earth’s oceans provides an effective buffer against much of the Sun’s harmful radiation.

a. As well as a conduit for the vital distribution of oxygen and hydrogen molecules across the planet, the Earth’s oceans provide an effective buffer
b. Besides a conduit for vital distribution of oxygen and hydrogen molecules across the planet, also the Earth’s oceans provide an effective buffer
c. Besides a conduit for the vital distribution of oxygen and hydrogen molecules across the planet, the Earth’s oceans also provide an effective buffering
d. The Earth’s oceans provide not only a conduit for the vital distribution of oxygen and hydrogen molecules across the planet, but also an effective buffer
e. The Earth’s oceans not only provide a medium for the vital distribution of oxygen and hydrogen molecules across the planet but also an effective buffer

I Chose the OA only but, I couldn't also find anything wrong with C, Just that the usage of "also" seems unnecessary. Please help!!

C has a meaning and usage issue.

If C were to be correct, it should be worded as:
Besides providing a conduit for the vital distribution of oxygen and hydrogen molecules across the planet, the Earth’s oceans also provide an effective buffering against much of the Sun’s harmful radiation.
I think even " being " will make sense.

Besides is used as preposition and must be followed by a noun or a noun phrase. In that respect C is correct but meaning wise it is wrong because the prepositional modifier does not clearly modifies the Earth's oceans.

What is the OE?

can we eliminate option C as it uses buffering? is "provide an effective buffer" needed?

a. As well as a conduit for the vital distribution of oxygen and hydrogen molecules across the planet, the Earth’s oceans provide an effective buffer --- ---The preposition ‘as well as’ has to be to be followed by a gerund such as providing, if an action is required to be stated after the ‘as well as’; the gerund is missing in the choice.

b. Besides a conduit for vital distribution of oxygen and hydrogen molecules across the planet, also the Earth’s oceans provide an effective buffer—'besides ---also' --- redundant

c. Besides a conduit for the vital distribution of oxygen and hydrogen molecules across the planet, the Earth’s oceans also provide an effective buffering. ------1. 'Besides ---also' --- redundant 2. Buffering is a wrong word. buffer is the correct one

d. The Earth’s oceans provide not only a conduit for the vital distribution of oxygen and hydrogen molecules across the planet, but also an effective buffer --- proper correlative parallelism of ‘not only – but also’ maintained. Correct choice

e. The Earth’s oceans not only provide a medium for the vital distribution of oxygen and hydrogen molecules across the planet but also an effective buffer -- ‘not only provide – but also an effective’ -- not parallel

I agreed with the explanation of C ; but in D the usage of comma before but isnt that unnecessary ;

A comma should be placed before the word " but " only if but is at the beginning of an independent clause. IN d this is not the case ; Does that make D wrong or the what i believe is the usage of comma for but wrong.

D is best choice choice
As per intent of sentence , The earth oceans provide 2 things - Oxygen and hydrogen molecules + Buffer against radiation
D summarize the same very well
