Answer:
Humorous tone.
Step-by-step explanation:
Tone is the attitude that the speaker or writer has while saying or writing something. Tone can be of a serious one, or sad, happy, hilarious, or even accusatory, among others.
In the given sentence, the speaker reveals that "George was in no hurry, apparently". The inclusion of the word "apparently" makes it a sarcastic or even hilarious one.
So, the tone is humorous.
