In a mathematical  expression   when as negative vale is been used to multiply a negative value, then we will have a positive values , same thing with when a negative value is used to multiply a positive value, a negative value will be gotten.

In the case of the question, if positive value is used to divide a negative value, a negative value will be gotten, hence  expression that is equal to -4 is  16/-4 which is means  optionD  is correct.

Therefore, option C is correct.
