What is the author’s tone in a piece of writing?

a. the author’s attitude toward the topic
b. the quality and strength of the writing
c. the subject or topic of the writing
d. the author’s knowledge of the topic

Hi!

An author's tone is basically their overall feeling or attitude toward a topic. The tone can be anything from angry, happy, or even sad. 

Here's an example:

'And just like that, she left. The walls of melancholy arose; closing in on me once more. I stood alone'. 

You would say that the tone in this passage would be of sadness. 

Hopefully, this helps you! =)

Ithink the answer is c. detached.
