The correct choice is C because it chains the replace method to replace all occurrences of 't', 'o', and 'y' with their uppercase counterparts. This will create the desired output of "a TOYOTa." Option A is incorrect because it only replaces part of the string and is missing quotation marks around the second parameter. Option B is incorrect because it only replaces the first occurrence of 't' with 'T', and the third option replaces a substring of the original string which is not what we want.
