The Correct Option is C

Solution and Explanation

Step 1: Recall the geographic distribution of these arboviral diseases.
All four are arthropod-borne, but their endemic ranges differ.

Step 2: Evaluate each option.
West Nile fever is reported in India and is transmitted by Culex mosquitoes.
Dengue is highly endemic across India and is transmitted by Aedes aegypti.
Sandfly fever is present in India and is transmitted by Phlebotomus sandflies.
Yellow fever is confined to tropical Africa and South America. It has never been recorded in India or Asia, despite the presence of the competent Aedes aegypti vector, which is why India enforces strict yellow fever vaccination requirements for travellers from endemic zones.

Step 3: Conclusion.
Yellow fever is the arthropod-borne disease absent from India (option C). This matches the printed key.
