Final Answer:
The ice skater in question 7934 likely weighs b) 50 kg.
Step-by-step explanation:
Determining the weight of an individual, including an ice skater, requires considering the typical range of human weights.
Option b) 50 kg is a reasonable estimate for an average adult's weight, including that of an ice skater.
The options a) 50 g, c) 5 kg, and d) 500 kg are not within the typical human weight range, making them less likely.
In this context, the question assumes a realistic weight for an ice skater, and 50 kg aligns with common human weights.
It is important to note that the actual weight of an individual can vary, but for the purpose of this question, the most plausible answer is b) 50 kg.
