Final answer:
Selvam would most likely play the role of a housekeeper in relation to Kenny.
Step-by-step explanation:
Selvam's role in relation to Kenny can be determined based on the given options. An assistant surgeon assists the main surgeon during operations, but there is no indication that surgery is involved in their relationship. A chef is responsible for preparing food, but again, there is no mention of food or cooking in the question.
A translator bridges the communication gap between people speaking different languages, which could be a possibility if Selvam and Kenny do not speak the same language. However, the most relevant and likely role Selvam would play in relation to Kenny is that of a housekeeper. A housekeeper is responsible for cleaning and maintaining a household, which could involve taking care of Kenny's living space and other domestic tasks.
