This eliminates options B and C.
Possibility 2.
As India has limited infrastructure for reading facilities in libraries, it is essential to allow content to be delivered to students in order to expand domain of their knowledge. This formation also implies the intended meaning and is both grammatically and contextually correct.
Possibility 3.
Allowing content to be delivered to students in order to expand domain of their knowledge, India has limited infrastructure for reading facilities in libraries. Though the above construction is grammatically correct yet it doesn’t make a coherent sentence.
