Answer:
If they are looking for one BEST answer, it is the water. 
If looking for top two, it is water and soil. 
Realistically, however, this disposal can contaminate all 3. 
Let me explain:
The motor oil that is dumped on a driveway first makes its way into the soil. The freshwater found in this soil becomes contaminated with motor oil and can eventually runoff into the ocean. Once this liquid evaporates, it then becomes air pollution. Shortest, best answer tho is water. 
Hope this helps. Have a great day!
 
        
             
        
        
        
Answer:
characterized by presence or absence of antigens
the blood types are A, B, O, AB
Explanation:
There are two antigens and two antibodies that are mostly responsible for the ABO types.  The specific combination of these four components determines an individual's type in most cases. Erythrocytes and serum were related to the presence of antigens on these erythrocytes and antibodies in the serum. these antigens  are A and B, and depending upon which antigen the erythrocytes express, blood either belonged to blood group A or blood group B. A third blood group contained erythrocytes that reacted as if they lacked the properties of A and B, and this group was later called "O" blood group. The fourth blood group AB, was added to the ABO blood group system. These erythrocytes expressed both A and B antigens. 
Blood group   Antigen present on RBC    Antibodies in serum    Genotype(s)
       A                        antigen A                             anti-B                     AA or AO
       B                        antigen B                             anti-A                     BB or BO
       AB              both A and B antigen                 none                         AB
       O                           none                           anti-A and anti-B           OO
