(1) Acceptance of goods occurs when the buyer
       (a) after a reasonable opportunity to inspect the goods signifies
           to  the  seller that the goods are conforming or that he will
           take or retain them in spite of their non-conformity; or
       (b) fails to make  an  effective  rejection  (subsection  (1)  of
           Section 2--602), but such acceptance does not occur until the
           buyer has had a reasonable opportunity to inspect them; or
       (c) does any act inconsistent with the seller's ownership; but if
           such  act  is  wrongful  as  against  the  seller  it  is  an
           acceptance only if ratified by him.
  (2) Acceptance of a part of any commercial unit is acceptance of  that
entire unit.
