Right choice is (b) 1950s

To elaborate: Retort pouch was first developed in 1950s. A retort pouch is a packaging material, composed of different layers – Polypropylene (food contact layer), Nylon (Abrasion Resistance layer), Aluminium foil (Barrier Layer) and Polyester (outside layer). In 1950s, the retort pouch for heat-processed foods was developed originally for the US military, to pack Ready to Eat food items.
