You have a large dataset stored as a CSV file, and you want to load, clean, and prepare it for a machine learning model using Python. What steps should you take using Pandas to clean the data and remove any rows with missing values?
Response:

• A. Use np.load() to load the data and ignore any missing values
• B. Visualize the missing values with Matplotlib before cleaning the data
• C. Use the pd.read_csv() function to load the data, followed by the dropna() function to remove rows with missing values, and the describe() function to get summary statistics for further analysis
• D. Load the data with pd.read_csv() and manually remove missing values from the file
