Final answer:
The correct answer is City B for the city whose temperature is closest to 0°C, and City C for the city whose temperature is farthest from 0°C, corresponding to Option 1: City B, City C.
Step-by-step explanation:
The student's question is focused on identifying which cities have temperatures closest to and farthest from 0°C. To determine this, we review the given temperatures for each city: City A (-10°C), City B (-1°C), City C (-20°C), and City D (-2°C). We need to find the absolute values of these temperatures to understand how close or far they are from 0°C.
Comparing these absolute values:
- City A: 10°C away from 0°C.
- City B: 1°C away from 0°C — closest to 0°C.
- City C: 20°C away from 0°C — farthest from 0°C.
- City D: 2°C away from 0°C.
Therefore, the correct answer is City B for the city whose temperature is closest to 0°C, and City C for the city whose temperature is farthest from 0°C. This corresponds to Option 1: City B, City C.
