Final answer:

Step-by-step explanation:
Human performance is influenced by a combination of aptitude, training, and motivation. Aptitude refers to a person's natural abilities or talents in a particular area. Training enhances skills and knowledge, while motivation provides the drive and incentive to perform well. When aptitude and training are combined and multiplied by motivation, it results in improved human performance.
For example, let's say someone has a high aptitude for playing the piano and receives extensive training from a skilled teacher. However, without the motivation to practice regularly and strive for excellence, their performance may not reach its full potential. On the other hand, someone with moderate aptitude and training but a strong motivation to succeed may outperform someone with higher aptitude and training but lower motivation. Therefore, The correct answer is D) (Aptitude + training) * motivation.
