5. The Heisenberg Uncertainty Principle is generally applied to very small objects such as electrons and protons. Which of the following statements best explains why don't we use uncertainty principle on larger objects such as cars and tennis balls?
(A) The errors of a measurement can always, in principle, be made smaller by using more sensitive equipment.
(B) Large objects at any instant of time have an exact position and exact momentum and with sufficient care we can measure both precisely.
(C) Large objects obey Newton's laws of motion, to which the uncertainty principle does not apply.
(D) Because it does apply to large objects, but the uncertainties are so small that we don't notice them.
(E) None of above is correct.
