Answer:
A). Doctrine of the resurrection of the dead.
Step-by-step explanation:
Pauline epistles or the letters to the Romans comprises the sixth book of new testament composed by Apistle Paul. It elaborates the concept of salvation(which is an after death thing) which according to him can be attained only by the gospel of Christ. These letters are considered to be the clearest and the most coordinated representation of Christian doctrine among all the sculptures. It echoes the rebellious nature of humans against god which he regards as 'sinfulness of humanity'. He illustrates that it is the almighty's grace over their son that they attain redemption or salvation as a symbol of being justified by him for their deeds. Thus, to conclude it could be regarded as the doctrine of resurrection of dead.
