One Reason for Including Classical Texts in the Education of Christians

One reason for including classical texts in the education of Christians by the fourth century was:

A) the failure of the Church to win new adherents once it had been legalized by the state.
B) the lack of any Christian texts that could allow converts to understand the Christian articles of faith.
C) the lack of any Christian texts on mathematics,ethics,or logic.
D) the desire of Christian intellectuals to be regarded as philosophers and to make classical learning applicable to a Christian way of life.
E) to show that classical pagan beliefs could be reconciled without difficulty with Christian beliefs.
