Answer
Exam answer
(d) toUpperCase(char).
Explanation
Two things must be right: the spelling and the argument. Java is case-sensitive, so the name is exactly toUpperCase — with a capital U and a capital C — which rules out options (b) and (c). And the Character version must be told WHICH character to convert, so it takes a char argument. The full call is Character.toUpperCase(ch).
In words
toUpperCase(char).
