b. Linguistic relativity
c. Mental sets
d. Availability heuristic

a. Functional fixedness

Explanation:

Functional fixedness is a cognitive bias in which one views an approach to a problem in just a single way that is common, while failing to consider the possibility of discovering other approaches to solve a problem. In order words, it explains that the possibility of one finding other ways an object can be useful is hindered by the already known intended uses of that object.

MacGyver, a fictional TV hero who uses duct tape, chewing gum and some luck, is an example of how functional fixedness is overcomed.
