Which one of the following diseases is not transmitted by tiger mosquitoes?

Correct answer: (d) Japanese Encephalitis

Explanation

Tiger mosquitoes (Aedes) transmit yellow fever, dengue, chikungunya and Zika.

Japanese Encephalitis is caused by a flavivirus spread by Culex mosquitoes that breed in rice fields, not by Aedes.

Hence Japanese Encephalitis is the disease not transmitted by tiger mosquitoes.
