Which of these statements is true about slicing strings?1 pointThe slice() method can be used to slice a string.If the starting index is negative, Python generates a runtime error.If the starting index is negative, Python counts backward from the end of the string.When slicing a string, you must always provide both the starting and ending indexes.
