The stress-strain graph of an elastomer such as tissue of aorta is as shown in the diagram. From the graph which of the following can we infer? As stress increases 

• A

  strain increases and modulus of elasticity decreases

• B

  strain increases and modulus of elasticity increases

• C

  strain decreases and modulus of elasticity decreases

• D

  strain decreases and modulus of elasticity increases
