Answer: Filtering
Step-by-step explanation:
Filtering in communication occurs when information passed on between two bodies is being reduced by the middlemen, where the middlemen are not able to communicate favourable with either party and it affects either of the party, it's called filtering. The inability for the salesperson's to communicate the technical knowledge of the product to the customers which they are being taught during trainings is known as filtering in communication. This causes the business loss as the customers are not able to operate the equipment effectively which the business sells.
