Answer:
A. Map of Kerala
Read Explanation:
Maps (Physical and Political): Political maps are the most effective visual aids to distinguish administrative boundaries, such as coastal versus landlocked districts.
The Political Map of Kerala is the most suitable study tool to identify the boundaries of the 14 districts of Kerala and whether they share a border with the Arabian Sea.
Map of India / World Map: Although these show the location of Kerala, the boundaries of the districts of Kerala or the details of the coastline are not clearly understood.
Globe: Although it is a model of the Earth, Kerala is only a very small part of it. The globe will not help in identifying the districts.
Additional information: Out of the 14 districts of Kerala, 5 districts do not have a coastline (Wayanad, Palakkad, Kottayam, Idukki, Pathanamthitta). The remaining 9 districts have a coastline.
