(E) therefore being the most elusive of submarines, it is increasingly viewed

Please explain what is the difference between C and E.. i mean i selected the right option but wanna know the exact meaning of the 2 statements..

We need a conjuction "and" to separate the 2 clauses. Also, E uses the word "being", which GMAT does not prefer most of the times .
