Let $X$ be a 3-variable Boolean function that produces output as ' 1 ' when at least two of the input variables are ' 1 '. Which of the following statement(s) is/are CORRECT, where $a, b, c, d, e$ are Boolean variables?

$X(a, b, X(c, d, e))=X(X(a, b, c), d, e)$

$X(a, b, X(a, b, c))=X(a, b, c)$

$X(a, b, X(a, c, d))=(X(a, b, a)$ AND $X(c, d, c))$

$X(a, b, c)=X(a, X(a, b, c), X(a, c, c))$
