str.startswith(prefix[, start[, end]])  Return True if string starts with the prefix, otherwise return False. prefix can also be a tuple of prefixes to look for

Correct answer is : B

"from" string available at index 23 and 27.

str.endswith(suffix[, start[, end]]) - With optional start, test beginning at that position. With optional end, stop comparing at that position.

so 'from' stops at 27 , so it will match endswith

Correct answer is : B

str.endswith(suffix[, start[, end]]) Return True if the string ends with the specified suffix, otherwise return False. suffix can also be a tuple of suffixes to look for

"e" string ends with "UK" and suffix_strings contain " UK" and "IND". So  e.endswith(suffix_strings) prints True

"p" string does not end with any of " UK" and "IND". so p.endswith(suffix_strings) prints false
