The right answer here would be A - the phrase 'modulate your voice'
refers to a need to vary your voice's properties. Modulating means
changing the pitch or tone, and can be used referring to one's voice, or
to an instrument. You can modulate both up or down, and this usually
involves changing the key signature in which you are playing or singing.

Doodle (the baby) is treated in ironic way in many situations in the play "The Scarlet Ibis" by James Hurst. For example, when he is born his mother ask for the building of a coffin for him. This is rare because no mother expects his baby dies. Since the baby does not die, the coffin is stored. Another example of irnony is that "Brother" expects Doodle to learn how to walk and talk before he could be able to do it. Brother thinks this is a way to help his little brother but in the process he pushes Doodle so hard that the young boy dies.
The big irony is that when they expected the baby dies he lived and when Doodle is forced to perform the above mentioned activities, he dies. Probably Doodle would have lived longer if everyone accepted him as he was.
