Correct Option (A)
The passage describes political development as a process that disrupts traditional institutions and loyalties, leading to ambivalent situations. This involves some individuals renewing traditional identifications while others align with new groups. The fostering of diverse group awarenesses (class, tribe, region, etc.) further illustrates that this process is not straightforward or single-directional. Therefore, political development is characterized by both the strengthening of certain elements (growth) and the transformation or weakening of others (decay), making it a non-unilinear phenomenon.
Incorrect Options:
Option (B): The passage indicates diverse responses to political development, including both reaffirmation of traditional ties and adoption of new ones. It does not claim that traditional societies universally resist or succeed in resisting the positive aspects of development.
Option (C): The passage explicitly states that "others align themselves with new groups and symbols," which directly contradicts the assertion that it is impossible for traditional societies to break away from lingering loyalties.
Option (D): The passage identifies the sustenance of traditional loyalties as one possible outcome of political development's disruptive nature. However, it does not establish a causal link suggesting that such sustenance is inherently beneficial or "conducive" to political development. The text describes a complex process fostering various group awarenesses, not necessarily promoting traditional loyalties as a driver of development.
