Answer:
B)-3°C < 1°C
Explanation:
Since, the symbols of inequality are,
'>' more than
'<' less than
If we say something is cooler than it means it is lesser than other according to its temperature,
That is, ice cream -3°C is cooler than ice cream at 1°C,
⇒ temperature -3° C is less than temperature 1°C
⇒ -3° C < 1°C
Which is the required inequality,
Option 'B' is correct.
