Step 1: Understanding the Question.
Sentence i opens the paragraph and sentence vi closes it. Sentences ii, iii, iv and v go in between.
Step 2: Key Approach.
Two things decide this jumble. First, the pronoun "he" in the fixed last sentence must refer to a man named immediately before it. Second, the paragraph names three Indian figures, and history normally runs oldest to newest.
Step 3: Fixing the last middle sentence.
Sentence vi says "he shook the foundation of the British rule in India through non-violence". Only a man who fought the British fits, and that is Mahatma Gandhi. Sentence v ends with his name, so v must be the fourth middle sentence, sitting right before vi. That alone rules out options (A) and (B), which end with iv and v respectively in different places, and rules out (C), which puts v first.
Step 4: Ordering the first three middle sentences.
Sentence i says India's message has always been one of love and peace, and "it" in sentence iii refers to that message: "it has been a source of light and wisdom to the rest of the world". A pronoun sits close to its antecedent, so iii follows i.
The paragraph then gives examples. Sentence ii names the Buddha, who lived in the sixth century BCE. Sentence iv names Ashoka, who ruled in the third century BCE. Sentence v names Gandhi in the twentieth century. Oldest first gives ii, then iv, then v.
The word chain also supports this: iii speaks of "light and wisdom", and ii calls the Buddha "the light of Asia", so ii sits right after iii.
Step 5: Reading the full paragraph and checking the rest.
i, iii, ii, iv, v, vi reads: India's message is love and peace, it has lit up the world, the Buddha was the light of Asia, Ashoka took up non-violence after Kalinga, Gandhi was the greatest apostle of non-violence in recent years, and he shook British rule with it. The middle order is iii, ii, iv, v.
Option (A) ii, v, iii, iv places Gandhi second and Ashoka last, so the chronology is scrambled and "he" in vi would refer to Ashoka.
Option (B) iv, ii, iii, v puts Ashoka before the Buddha and drops the general statement iii in the middle of the list of people.
Option (C) v, iv, iii, ii runs the history backwards and leaves "he" in vi pointing to the Buddha.
Final Answer:
The correct sequence of the middle sentences is iii, ii, iv, v, which is option (D).
