Option 2 : 1 and 2 only

The correct answer is 1 and 2 only.

Concept:

Vector-borne diseases

Vector-borne diseases are human illnesses caused by parasites, viruses and bacteria that are transmitted by vectors.
The burden of these diseases is highest in tropical and subtropical areas.
Vector-borne diseases like Dengue, Malaria, Chikungunya, Yellow fever and Zika have major outbreaks since 2014.
Pathogen transmission mostly takes place through global travel and trade, unplanned urbanization and climate change.
Bed bugs are not known to spread disease. Hence 4 is incorrectly matched.

Main vectors and diseases they transmitted are:

Vector	Disease
Aedes mosquito	Chikungunya. Hence 1 is correctly matched Dengue fever Lymphatic filariasis Rift Valley fever Yellow fever Zika
Anopheles mosquito	Malaria. Hence 1 is correctly matched Lymphatic filariasis
Culex mosquito	Japanese encephalitis Lymphatic filariasis West Nile fever
Sandflies	Leishmaniasis( Kala-Azar) Sandfly fever (phlebotomus fever)
Ticks	Crimean-Congo haemorrhagic fever Lyme disease Relapsing fever (borreliosis) Tick-borne encephalitis Tularaemia
Triatomine bugs	Chagas disease (American trypanosomiasis)
Tsetse flies	Sleeping sickness (African trypanosomiasis). Hence 3 is incorrectly matched
Fleas	Plague (transmitted by fleas from rats to humans) Rickettsiosis
Black flies	Onchocerciasis (river blindness)
Lice	Typhus and louse-borne relapsing fever

Consider the following three statements about link state and distance vector routing protocols, for a large network with 500 network nodes and 4000 links. [S1] The computational overhead in link state protocols is higher than in distance vector protocols. [S2] A distance vector protocol (with split horizon) avoids persistent routing loops, but not a link state protocol. [S3] After a topology change, a link state protocol will converge faster than a distance vector protocol. Which one of the following is correct about S1, S2, and S3?
