Explanation:

Recently, Kerala Forest Department has framed guidelines for snake handling. By doing so, it has become first to institutionalise snake handling in the country.

• The move to certify snake handlers comes amid allegations of unscientific approaches by snake catchers that tend to create stress to the animal and pose risk to their and others’ lives. Kerala has reported 334 deaths and 1,860 other cases of snake-bites in the past three years.
• The guidelines make it mandatory for snake handlers, aged between 21 and 65 years, to seek certification. The applications will be screened by the Assistant Conservators of Forest (ACF, Social Forestry) to prepare lists of snake handlers in each district.
• Those short-listed will be required to undergo a mandatory training on safe and scientific handling of snakes.
• While the certification will be valid for five years, the respective ACFs can withdraw or cancel the same if the snake handler is found to be involved in any illegal or unethical practices.
• Rescued snakes will also have to be released in the presence of forest officials at the earliest. If found injured, the snake can be released only after ascertaining its fitness. Non-native species, however, cannot be released and have to be handed over to the Forest Department.

Hence option 4th is correct.
