The inequality x < -5 represents all real numbers less than -5, and the inequality x > 4 represents all real numbers greater than 4. The union of these two sets includes all real numbers that satisfy either inequality, which is exactly what choice C represents. None of the other choices include all values that satisfy the given inequality.
