Final answer:
The word 'agitated' best describes Kumalo's state when he sees Jarvis in 'Cry, the Beloved Country,' as it reflects his deep emotional turmoil.
Step-by-step explanation:
In the novel Cry, the Beloved Country, the word that best describes Kumalo's state when he sees Jarvis is agitated. Kumalo is engulfed by a mix of emotions, given the complex circumstances that surround his relationship with Jarvis, especially after the tragedy involving Jarvis's son. The rest of the choices -- surprised, joyful, and indifferent -- do not accurately capture the depth of anxiety and turmoil that Kumalo experiences in that moment.
