Hence, the correct answer is option “C”.

Expert Solution & Answer

Explanation of Solution

Semicolon (;):

Semicolon is a type of command in Java.

The semicolon is used to indicate to the compiler that the command ends here.
Semicolon is used as delimiter in Java to intentionally separate a command from the following Java command.
If a semicolon is missed in any of the statements, then the program produces an error.

Example for the purpose of Semicolon (;):

//Declare and initialize the variables

double value1 = 28;

double value2 = 32;

double value3 = 37;

The above three variable declaration statements are all individual commands separated by the semicolon.

Explanation for incorrect options:

a. Period:

Period is used differentiate an integer value and decimal value, the value with the period is considered as decimal value.

Hence, the option “A” is wrong.

b. Parentheses:

Parentheses are the symbol used to group the statements in if statement, loop or any other control structures.

Hence, the option “B” is wrong.

d. Ending brace:

Braces are used to represent a block of code, ending brace represents that the block of code ends there.

Hence, the option “D” is wrong.
