Explanation

Carnauba wax- The leaves of the carnauba palm, Copernicia cerifera that grows in Brazil, have a thick coating of wax, which can be harvested from the dried leaves. It contains mainly wax esters (85%), accompanied by small amounts of free acids, alcohols, hydrocarbons and resin that is called as carnauba wax. Vegetable ivory is named for its resemblance to elephant ivory. Species in the genus Phytelephas, native to South America are the most important sources of vegetable ivory. Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of the oil palms, primarily the African oil palm Elaeis guineensis. Castilla elastica, commonly is known as the Panama rubber tree, is a tree native to the tropical areas of Mexico, Central America, and northern South America. It was the principal source of latex among the Mesoamerican peoples in pre-Columbian times. The latex gathered from Castilla elastica was converted into usable rubber called Panama rubber. Hence, the correct sequence of codes P - 2, Q - 1, R - 4, S - 5 is.
