Final answer:
Without additional context or text featuring Mike addressing Luke, it is impossible to determine what Mike says to Luke among the provided options.
Step-by-step explanation:
The question appears to be from an English subject, specifically a reading comprehension or literature section. The scenario likely comes from a narrative where characters are interacting. Given that there is no context or text provided that includes dialogue from a character named Mike addressed to Luke, it is impossible to accurately choose one of the given responses (a-d) as something Mike says to Luke.
