Final answer:
Brabantio is not pleased with Desdemona's marriage to Othello in Shakespeare's play; he is outraged, accusing Othello of using witchcraft to win Desdemona's love.
Step-by-step explanation:
The statement "Desdemona's father Brabantio is pleased that his daughter had decided to marry Othello" is actually incorrect. In William Shakespeare's play Othello, Brabantio is in fact displeased and outraged when he discovers that his daughter has married Othello, a Moorish general in the Venetian army. The play delves into themes of racism, love, jealousy, and betrayal, which are evident from the very beginning when Brabantio accuses Othello of witchcraft for winning his daughter's love. It is important to closely read and interpret literature to understand the dynamics between characters and the themes conveyed by the author.
