WILL GIVE BRAINLIEST! A study routine includes a. studying at different times everyday. c. having a set location to study. b. an isolated location away from everyone. d. studying at the same time once a week.

Your correct answer is option A. studying at different times everyday

Explanation:

Option B is very incorrect because you don't have to have a certain location to study at. You can study anywhere at anytime.

Option C is also extremely incorrect because studying is not an isolated  vacation away from everyone. You can study with whoever you want when ever.

Option D is incorrect because you don't need to study at the same time once a week. It is better to study everyday for something but you don't have to have it at the same time every time. Nobody is on time for everything.
