The novel hybrid technology developed by the scientists at CSIR-NCL Pune, with support from the Water Technology Initiative of the Department of Science and Technology (DST), Government of India, is called SWASTIIK. This technology aims to provide safe and healthy drinking water.

Option 1: SafeWater - This option is not the correct answer. It is a generic term that refers to water that is safe for consumption, but it does not specifically denote the hybrid technology developed by CSIR-NCL Pune.

Option 3: Arsiron Nilogon - This option is not the correct answer. It is a term that does not relate to the hybrid technology developed by the scientists. It seems to be a made-up term.

Option 4: Fluoride Nilogon - This option is not the correct answer. While it mentions a specific element, fluoride, it does not correspond to the hybrid technology developed by CSIR-NCL Pune.

Therefore, the correct answer is option 2: SWASTIIK.
