B.

C.
Neither the manager nor the employees were present.
D.

Show Answer & Explanation

The dog, which was barking loudly, disturbed the neighbors.
B.
The dog which was barking loudly, disturbed the neighbors.

The dog, which was barking loudly disturbed the neighbors.
Show Answer & Explanation
Correct Answer: A
Option A correctly uses commas to separate the non-restrictive clause 'which was barking loudly' from the main clause. The other options either lack necessary commas or misplace them.
Q5
Medium
Choose the sentence that contains a misplaced modifier.
A.
She nearly drove her kids to school every day.

Running down the street, the cat was chased by a dog.
