A heuristic is a
A. "rule of thumb" that provides a best-guess solution to a problem.
B. procedure that is guaranteed to solve a problem.
C. series of rules that specify how we organize parts into wholes.
D. short algorithm.

The answer is A.

Explanation:

A heuristic can be described as the best immediately available solution to a situation, even if it's not the most optimal overall. Although they might help us make quick decisions, they might also result in misjudgement. They are often called "mental shortcuts":

Some examples of heuristics are the representativeness heuristic, in which a person attributes someone else's features as characteristic of a specific group; or the availability heuristic, in which a person only reccurs to readily available, especially recent information.

Explanation:

A heuristic is a "rule of thumb" that provides a best-guess solution to a problem.

Heuristics are a problem-solving method that uses shortest possible time to produce good-enough solutions normally a given a time frame or deadline must be met. Heuristics are a  technique used when wanting to make quick decisions, particularly when working with complex data. This does not mean the decisions made using an heuristic approach are top notch or necessarily optimal.
