Answer 1

Answer: (a) char ch = '\utea';

Explanation: A char literal may contain a Unicode character (UTF-16). We can directly use these characters only if our file system allows us, else use a Unicode escape (\u) such as "\u02tee". The char literals are always declared in single quotes (').

The option b, c, and d, are not valid because:

• In the option b), to make a String valid char literal, we should add prefix "\u" in the string.
• In the option c), single quotes are not present.
• In the option d), "\i" is used in place of "\u."

Hence, the correct answer is the option (a).
