Step-by-step explanation:
The correct answer is c) input_string.split('e', 2).
This option separates an input string on the first 2 occurrences of the letter 'e'. The split() function is used to split a string into a list of substrings based on a given delimiter, in this case, 'e'. The maxsplit parameter is set to 2, which limits the splitting to the first 2 occurrences of 'e'.
For example, if the input_string is 'elephant is an excellent animal', using input_string.split('e', 2) would result in ['', 'l', 'phant is an excellent animal']. The string is split into three parts at the first two occurrences of 'e'.
