Which of the following statements about engine size zero entries is true?

• A. There are no zero entries.
• B. There is exactly one zero entry.
• C. There are two zero entries.
• D. There are three zero entries.

Answer: (B)

In this dataset, engine size values are expected to be positive numbers. A value of zero typically marks missing or not-applicable data rather than a real engine size. If you look at the records and find exactly one row where engine size is 0, that means there is one zero entry in the column. That aligns with the statement that there is exactly one zero entry. If there were none, you wouldn’t see any zeros; if there were two or three, you’d see multiple rows with 0. So the correct interpretation is that there is one zero entry in the engine size column.
