Answer:
Humorous tone.
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 <em>"George was in no hurry, apparently"</em>. The inclusion of the word "apparently" makes it a sarcastic or even hilarious one.
So, the tone is humorous.
