Answer:
(a) Variable
Explanation:
In the programming world, a variable is used to store data that can be referenced and modified in a computer program. It typically refers to the label for the location (in memory) of a particular data used in programs. For example;
var b = 12.
This implies that the value 12 is stored in a location in memory that is labeled as b. Anytime the value 12 is needed either for retrieval or modification purposes, it can be referenced by simply calling the variable b.
