Correct -- it's C.
To determine which of the following sentence incorrectly uses a comma, we need to analyze each sentence individually. Here's an explanation for each sentence:
A. We had to decide among steak, lobster, and pork roast.
This sentence uses commas correctly. Commas are used to separate items in a list.
B. Before we could enter the building, we had to show our identification badges.
This sentence uses a comma correctly. It separates the dependent clause ("Before we could enter the building") from the independent clause ("we had to show our identification badges").
C. The car that was used as a demonstration in the race is owned by Cambridge Motor Company.
This sentence does not use a comma incorrectly. It does not require a comma because the relative clause "that was used as a demonstration in the race" is essential to identify which car is being referred to.
D. The tree, which has been part of the community for more than 75 years, was struck by lightning.
This sentence incorrectly uses a comma. The clause "which has been part of the community for more than 75 years" seems to provide additional, non-essential information about the tree. However, a comma is not the appropriate punctuation here. Instead, it should use a pair of dashes (—) or parentheses () to set off the non-essential clause.
Therefore, the sentence that incorrectly uses a comma is D.
