If the mobile number of your friend changes, and you often continue to dial his former number, it is an example of______________

Correct option is B

Negative transfer of learning: This occurs when previously learned knowledge or skills interfere with the acquisition of new knowledge or skills. In the case of dialing your friend's old number, your previously learned habit of using that specific number for communication is hindering your ability to adapt to the new number.
Positive transfer of learning: This happens when previously learned knowledge or skills facilitate the learning of new knowledge or skills. For example, if you previously learned to play the piano, you might find it easier to learn to play the guitar than someone who has no musical experience.
Zero transfer of learning: This means that previously learned knowledge or skills have no impact on the learning of new knowledge or skills. This is unlikely in most situations as prior experiences often influence how we learn new things.
Bilateral transfer of learning: This refers to the reciprocal influence between two different domains of knowledge or skills. It involves the application of knowledge or skills from one domain to enhance learning in another domain, and vice versa. While this phenomenon might be applicable in some scenarios, it doesn't directly relate to the situation described in the question.
