Answer:
1. The normal force acting upon the car is best represented by arrow <u>A</u>.
Reason:
The direction of normal force is always upward and opposite to gravitational force that why A is correct option.
2. The force of gravity acting upon the washers is best represented by arrow <u>B</u>.
Reason:
The direction of gravitational force is always downward toward the center of gravity and opposite to normal force that why B is correct option.
3. The applied force on the car is best represented by arrow <u>C</u>.
Reason:
The direction of applied force is along the direction in which it moves. that why C is correct option.
C. by observing them in their habitats

Nucleotides are joined together into strands, with the sugar and the phosphate groups switching places, to create strands of DNA.
<h3>What is human DNA called?</h3>
