Right choice is (b) False

To elaborate: An expression is a combination of variables, operators and functions. It is not necessary that only functions and variables are present in a mathematical expression. The statement ‘a=b+c’ contains no functions, but it only performs the addition operation between b and c and assigns the value to a. The statement a=sum(b,c) shows no mathematical operation explicitly since the operation is done by the function itself.
