Option 1 -> The passage discusses Halari donkeys specifically, not finding new milk sources.
Option 2 -> The passage explicitly states "the primary need is, of course, conservation" due to fewer than 500 Halari donkeys remaining.
Option 3 -> Boosting milk consumption is not mentioned; the focus is on preserving the breed.
Option 4 -> Skincare products are mentioned as a supplementary effort to sustain value, not the primary need.
Hence, Option 2: conservation of Halari donkeys -> The passage directly identifies conservation as "the pressing need" and "the primary need" with NRCE starting a dedicated conservation programme, especially given the critically low population of fewer than 500 animals -> correct
