A Correct answer
Explanation

parseFloat() parses a floating-point number from a string. parseFloat("8.56") returns the numeric value 8.56. Unlike parseInt(), parseFloat() continues parsing through the decimal point and subsequent digits until it reaches a non-numeric character. The alert will display "8.56".
