S1. Liberalisation changed the contours of India's economy. S2. India is today poised to become one of the top economies of the world. The second statement:

The first statement says liberalisation transformed India's economy. The second statement claims India is now poised to become one of the world's top economies. The second statement is a logical consequence/correlate of the first — the changes brought about by liberalisation are linked to India's current strong economic position. The statements do not contradict or contrast; they are not identical so 'coincides' is inaccurate. 'Correlates to the first' best captures the connection where the second statement relates to and follows from the first as a related outcome. Therefore (c) is correct.
