b. the temperature was - 5 degrees in the morning and rose by 5 degrees by 1:00 p.m.
c. the temperature was - 5 degrees in the morning and dropped by 10 degrees by 1:00 pm.
d. the temperature was 5 degrees in the morning and rose 5 degrees by 1:00 p.m.

Explanation:

Step1: Analyze option A

Initial temp is 5, drop 10. So $5 - 10=- 5$.

Step2: Analyze option B

Initial temp is -5, rise 5. So $-5 + 5=0$.

Step3: Analyze option C

Initial temp is -5, drop 10. So $-5-10=-15$.

Step4: Analyze option D

Initial temp is 5, rise 5. So $5 + 5 = 10$.

Answer:

B. The temperature was -5 degrees in the morning and rose by 5 degrees by 1:00 p.m.
