• C. Accurate; it is not necessary to be proficient in any task to be able to train.
• D. Accurate; the best trainers are often actually bumblers on the job, and are thus patient with new hires.

Answer: (B)

In professional training, you prove you can teach by combining solid mastery of the subject with solid teaching skills. The saying “those who can’t, teach” is a stereotype that misses what effective training really requires. A trainer must be proficient at the tasks being taught so demonstrations are accurate and credible, and they must be good at all aspects of training—planning, explaining concepts, guiding practice, giving feedback, and adapting to learners’ needs. That combination ensures learners can observe, understand, and apply what they’re taught. The other ideas fall short because one can be technically skilled but still struggle to teach effectively, or focus too narrowly on being an observer without actually guiding the learning process. Training needs both competence and instructional ability, not just one or the other.
