Both a and b will work.

A and be will not work because option a has semicolon and preprocessor doesn't have semicolon.
In option b the x is a lowercase argument and used as uppercase.

Is it not necessary to have a space in C?

How could option C be correct? There is no space between CUBE(X) and (X*X*X). Please someone explain it.

Option A will not be complile as between CUBE and (X) their is space
and their is no provision for double define value without \.

Semicolon and spaces between (x)and (x*x*x) makes option A wrong

It is working Properly...
#define CUBE(X) (X*X*X)
#define CUBE(X) (X*X*X);
#define CUBE(X)(X*X*X)
#define CUBE(X) (X*X*X)
#define CUBE(X) (X*X*X);
#define CUBE(X)(X*X*X)

Option B is the correct one... In preprocessor we can use lower cases also to define a function.. It is not compulsory to use higher cases..)
