Solution

The correct option is B -5
The initial temperature on Sunday was -19.
On Monday it was 14 degrees more.
To find the temperature on Monday, we have to add them together. But the numbers are having different signs.

-19+ 14

For that first find the difference between 19 and 14. We get 5.
Put the sign of the larger number. The answer is -5
-19 + 14 = -5 degree Celsius
