Solution

The valid declaration of a char from the options provided is:

d. char cr = '\u0223';

Explanation:

a. char ca = 'tea'; - This is not valid because a char can only hold a single character.

b. char ch = '\utea'; - This is not valid because '\utea' is not a valid Unicode escape sequence.

c. char cc = '\itea'; - This is not valid because '\itea' is not a valid escape sequence.

d. char cr = '\u0223'; - This is valid because '\u0223' is a valid Unicode escape sequence. In Java, you can use Unicode escape sequences to represent characters.
