Solution

The correct option is A Names of the scientists who developed the plasmid
The DNA molecule pBR322 was one of the first artificial cloning vectors (plasmid) constructed by Bolivar and Rodriguez.

Here, p stands for Plasmid, B for Bolivar, R for Rodriguez and 322 is the number given to this plasmid to distinguish it from other vectors they developed in their laboratory.
