Question

Which of the following is a complex sentence

A. of started to make pasta, but I changed my mind and made rice instead.
B. I enjoy reading because it's a solitary pleasure.
C. The dog was lonely; it barked all night.
D. Driving to work is more dangerous than walking.

Answer 1

I would also say A. I think you have a typo at the beginning of the sentences. It should be I started instead of Of started

The reason why it's A is because you have two sentences that have been combined by the conjunction but.
