Answer: `assert row_count == 10, 'Row count did not match'`
The correct answer is `assert row_count == 10, 'Row count did not match'`. This is because the `==` operator is used for equality comparison in Python, whereas `=` is an assignment operator. The `assert` statement does not require the `if` keyword. For more details, refer to the Python documentation on assertions.
