Answer: (c) Every real number is a complex number.

A statement is a declarative sentence that is either true or false, but not both. (a) is an opinion (its truth depends on the person judging), (b) is a question and (d) is an order, so none of them is a statement. Every real number \(a\) can be written as \(a + 0i\), so (c) is a declarative sentence with truth value T; it is a statement.
