Arrange the following events in sequential order as they happened in India : 1. Mahalanobis Model 2. Plan Holiday 3. Rolling Plan Select the correct answer using the code given below.

The events follow a clear chronological sequence in Indian planning history. The Mahalanobis Model was the cornerstone of the Second Five-Year Plan (1956–1961), emphasizing heavy industrialization and capital goods [2]. Following the Third Plan's failure due to the Indo-Pakistani war and severe droughts, the government implemented a 'Plan Holiday' consisting of three Annual Plans from 1966 to 1969 [3]. The Rolling Plan was introduced later in 1978 by the Janata Government after they terminated the Fifth Five-Year Plan a year early [3]. Therefore, the correct chronological order is the Mahalanobis Model (1956), followed by the Plan Holiday (1966–1969), and finally the Rolling Plan (1978–1980). This sequence corresponds to option 1.
