Sudhanshu has written the following code to create a DataFrame with boolean index :

import numpy as np
import pandas as pd
    df = pd.DataFrame(data = [[5, 6, 7]], index = [true, false, true]) 
    print(df)

While executing the code, she is getting an error, help her to rectify the code :

1. df = pd.DataFrame([True, False, True], data = [5, 6, 7])
2. df = pd.DataFrame(data = [5, 6, 7], index = [True, False, True])
3. df = pd.DataFrame([true, false, true], data = [5, 6, 7])
4. df = pd.DataFrame(index = [true, false, true], data = [[5, 6, 7]])
