After several defeats in wars, Robert Bruce went in exile and wanted to commit suicide. Just 

before committing suicide, he came across a spider attempting tirelessly to have its net. Time 

and  again,  the  spider  failed  but  that did not  deter  it to refrain from making attempts. Such

failures. Such act of the spider encouraged Bruce not to commit suicide. And then, Bruce went 

back again and won many a battle, and the rest is history. Which one of the following assertions 

is best supported by the above information?

A. Failure is the pillar of success
B. Honesty is the best policy
C. Life begins and ends with adventures
D. No adversity justifies giving up hope
