Option A: Wrong
This statement won't fly because it's a repetition if the question ''AS well as'' is a subordination to john i.e. complementary.

Option B: Right
This option appears and takes a valid tone because ''john'' in the statement acts as the object of the verb 'is'. it activates the inherent strength of grammatical cohesion and agreement.

Option C: Wrong
This statement is all wrong because the conjunction ''and'' used here does not conform with the phrase ''as well as'' used to co-join it.

Option D: Wrong
Here, ''john, as is also jane, is''. This is not obtainable in grammar. It is a grammatically deficient statement lacking in strength and vigor.

Option E: Wrong
This is wrong in entirety in this particular context. But correct grammatically if only it has not changed the semantics or the meaning of the original statement.
