Final answer:
The kinsman of the Prince and the suitor of Juliet preferred by Capulet, who behaves presumptuous toward Juliet after Capulet promises him he can marry her, is 2) Paris.
Step-by-step explanation:
The kinsman of the Prince and the suitor of Juliet most preferred by Capulet, who behaves very presumptuous toward Juliet after Capulet promises him he can marry her is Paris (option 2).
In Shakespeare's play Romeo and Juliet, Paris is a nobleman and relative of the prince who wants to marry Juliet.
Capulet initially favors Paris as a potential suitor for Juliet, and after Capulet promises Paris that he can marry Juliet, Paris becomes presumptuous in his behavior towards Juliet.
Examples of Paris's presumptuous behavior include his insistence on marrying Juliet even after she has expressed her love for Romeo, and his impatience and disrespectful attitude towards Juliet when she refuses to marry him.
