C In the first poem, the child is pure; in the second, he is corrupt.
In the Songs of Innocence, the child is depicted as pure and innocent, surrounded by sweet dreams, smiles, and angelic imagery. In contrast, the Songs of Experience portray the child as experiencing sorrow, secret desires, and the inevitability of growing up and facing the harsh realities of the world. The intersection of purity and corruption in these two poems shows the progression from innocence to experience, highlighting the loss of purity and innocence as one grows older.
