**Core Concept**
Filaria elimination in the South-East Asian region is a public health goal, which depends on the availability of effective drugs, vector control measures, and community involvement. The region has made significant progress in reducing the prevalence of lymphatic filariasis (LF) due to sustained efforts by national programs and international collaborations.

**Why the Correct Answer is Right**
The correct answer is that Filaria elimination is possible in South-East Asian region due to a combination of factors, including the availability of effective drugs like diethylcarbamazine (DEC), albendazole, and ivermectin, which are used in mass drug administration (MDA) campaigns. Additionally, vector control measures like insecticide-treated bed nets and indoor residual spraying (IRS) have been implemented to reduce the transmission of LF. Community involvement and education are also crucial for the success of filariasis elimination programs.
