Explanation
he sentence with a grammatical error is:
A) The physicist, along with her team, are conducting groundbreaking research.
The correct sentence should be:
The physicist, along with her team, is conducting groundbreaking research.
Here, the subject is "the physicist," which is singular.
Therefore, the verb should also be singular, "is."
The phrase "along with her team" is just additional information and doesn't change the subject's singularity.
