Problem solving is fostered by :

Correct option is D

(d) Divergent thinking is highly conducive to fostering problem-solving skills. Divergent thinking involves thinking in multiple directions and exploring many different solutions to a single problem. It encourages creativity, flexibility, and innovation, which are crucial for effectively solving problems, especially those that do not have straightforward answers.
Information Booster:
(a) Functional fixedness is a cognitive bias that limits a person to using an object only in the way it is traditionally used. It represents a barrier to problem-solving because it restricts the thinker’s ability to use known objects in novel ways, which can be essential for innovative solutions.
(b) Passive imitation involves copying others’ actions without understanding the underlying principles or adapting the actions to new situations. This can limit the development of problem-solving skills, as it does not encourage critical thinking or the application of knowledge to different contexts.
(c) Response Set (also known as set effect), refers to the tendency to approach problems in a habitual way. This can impede problem-solving when creative or new solutions are needed because it discourages thinking outside established patterns.
