We spent all day pulling weeds my back is sore. Which of the following makes this sentence correct? a. We spent all day pulling weeds, so my back is sore. b. We spent all day pulling weeds: my back is sore. c. We spent all day pulling weeds, my back is sore. d. We spent all day pulling weeds; because my back is sore.

The correct option is c. We spent all day pulling weeds, my back is sore.

Explanation:

The sentence mentioned in option C is properly punctuated. It has the comma at the right place and hence, option C is the best way to correct the sentence.

Other options, like option A, cannot be true because so and comma are being used at the same time in the sentence. The word so and comma should not come together.
