Solution
The correct answer is:
-
Variable names cannot start with a digit: This is true. In C, variable names must start with a letter or an underscore.
-

-
It is not an error to declare a variable to be one of the keywords (like goto, static): This is false. Keywords are reserved in C language and cannot be used as variable names.
-
They can contain alphanumeric characters as well as

There are certain predefined words as part of C programming language that have a special meaning and purpose. They are called reserved words or keywords.The user (programmer) cannot redefine these keywords, i.e.,the user cannot change their spellings or add new ones to the C programming language.All reserved words in C are formed using only the lowercase letters.Keywords have special meaning and purpose, so they cannot be used as variable names.C language has 32 reserved words as per ANSI standards. They are as given below:auto break case char const continue default do double else enum externfloat for goto ifint long register returnshort signed sizeof staticstruct switch typedef union unsigned void volatile whileSelect the correct statements from the given statements.ANSI C has 32 reserved words.Reserved words have predefined meaning in the system and they are known to the C compilerKeywords can be used as variable names.The meaning of keywords can be redefined.
