Option (a) is correct because the textbook explicitly states that 'The impact of globalisation is vastly uneven — it affects some societies more than others and some parts of some societies more than others.' This directly confirms that globalisation has been uneven in its impact on states and societies. Option (b) is incorrect as it contradicts the stated uneven nature of globalisation's impact. Option (c) is incorrect because globalisation is described as 'a multi-dimensional concept' with 'political, economic and cultural manifestations' — not confined to just the political sphere. Option (d) is incorrect as the context discusses cultural influences and resistance, but does not state that cultural homogeneity is an inevitable result of globalisation.
