No.

You need the three reasons to be parallel. That means each of the three has to be constructed just like the others.

No. Look for parallel structure.

B is right.

Thanks

Funny answer bonus:

Well, Francina certainly has a lot going on while she's trying to study! It's like a symphony of distractions. Her friends are calling her, her brother's stereo is blasting, and her dad is out there mowing the lawn like it's a race. It's a wonder Francina managed to concentrate at all!

b. While studying for her psychology test, Francina had trouble concentrating because her friends were calling her, her brother was blasting his stereo, and her dad was mowing the lawn.

To identify the correct sentence, we need to look for proper verb tense and sentence structure. In option a, the verbs "calling," "blasting," and "mowing" are all in simple present tense. However, in option b, the verbs "were calling," "was blasting," and "was mowing" are in past continuous tense, which is appropriate for describing actions happening at the same time in the past. Option c has a similar structure to option b but is less concise. Option d has incorrect verb tense, as "mowing" should be in the continuous form, just like in options b and c. Therefore, the correct sentence is b.
