Answers & Comments
Answer:
B) II only
Step-by-step explanation:
A temperature increase of 1°C is equal to a temperature increase of 1.8°F, so the second statement is true. However, the other statements are incorrect. A 1°F increase is equivalent to a 0.556°C increase, not 1.8°C.
So, the correct answer is B, II only.
