Explanation:

All the statements are correct.

• The Basel Convention: It came into force in 1992, intended to reduce transboundary movements of hazardous waste from developed to less developed countries (LDCs), and ensure their safe disposal as closely as possible to the source of generation.
• Rotterdam Convention: It covers pesticides and industrial chemicals that have been banned or severely restricted for health or environmental reasons by Parties and which have been notified by Parties for inclusion in the Prior Informed Consent (PIC) procedure.
• The Convention creates legally binding obligations for the implementation of the Prior Informed Consent (PIC) procedure.
• Stockholm Convention: It is a global treaty to protect human health and the environment from Persistent Organic Pollutants (POPs).

Hence option 4th is correct.
