(D) Let the number of officers be $x$. Then,the number of the rest of the staff is $(500 - x)$.According to the problem,the total salary of all staff is the sum of the total salary of officers and the total salary of the rest of the staff.Total salary of all staff $= 500 	imes 5,000 = 2,500,000$.Total salary of officers $= x 	imes 14,000$.Total salary of the rest of the staff $= (500 - x) 	imes 4,000$.Setting up the equation:$14,000x + 4,000(500 - x) = 2,500,000$Dividing the entire equation by $1,000$ to simplify:$14x + 4(500 - x) = 2,500$$14x + 2,000 - 4x = 2,500$$10x = 2,500 - 2,000$$10x = 500$$x = 50$.Therefore,the number of officers is $50$.
