Option 1 -> Places "over their neatly worn silk sarees" between the subject and main verb, disrupting the sentence flow.
Option 2 -> Creates a smooth narrative: "As he made his way across the hall, Murugan noticed that both the women had press tags pinned to their shoulders over their neatly worn silk sarees" - logically describes the observation sequence.
Option 3 -> Incorrectly positions "over their neatly worn silk sarees" before introducing Murugan and the women, causing confusion.
Option 4 -> Completely scrambles the sentence structure, making it grammatically incorrect and meaningless.
Hence, Option 2: (B), (A), (D), (C) -> The sentence follows natural narrative order: the temporal clause (as he walked), the subject and observation (Murugan noticed), what was noticed (press tags on shoulders), and finally the descriptive detail (over their sarees) -> correct
