"Am I the master here, or you? Go to"
Capulet asks this rhetorical question to Tybalt in order to put him in his place. Capulet is Tybalt's elder and Tybalt is speaking as though he will ignore his uncle's wishes. Capulet reminds Tybalt that he is the one in charge, not Tybalt. Capulet reminds Tybalt of his position at the beginning of this excerpt as well when he says "It is my will; the which if thou respect". Here he is telling Tybalt that he wants Tybalt to leave Romeo and his friends alone. If Tybalt respects Capulet, he'll not engage in a fight with the Montagues at the party.
It is just something added at the start of a word. For example IC-onic (iconic)
B would be the right answer because it is past tense.
Soft tired tone because in the sentence you can get a vibe that he/she is tired.
