The correct answer is B. Rote learning.
Rote learning is a method of learning by repetition. It is a passive form of learning that does not require the learner to think critically or understand the material. Rote learning can be effective for memorizing facts, but it does not help the learner to develop their understanding or problem-solving skills.
Guided learning is a method of learning that is supported by a teacher or other expert. Guided learning can be effective for helping learners to understand and apply new concepts. Assisted learning is a method of learning that is supported by technology. Assisted learning can be effective for providing learners with individualized instruction and feedback. Fast learning is a method of learning that is focused on speed. Fast learning can be effective for learners who want to learn a lot of information quickly, but it does not necessarily lead to deep understanding.
In conclusion, rote learning is the only method of learning that does not help the mental growth of a student.
