Answer: b. Friar Laurence
Explanation:
In literature, there are two types of characters: round and flat.
Round characters are complex, well developed, and the audience is given an insight into their traits. These characters are often involved in the main plot of a literature work.
Flat characters, on the other hand, are not well developed, and we find out very little about them from the story.
In this particular Shakespeare's play, there are many round characters: Romeo, Benvolio, Mercutio, Friar Laurence, Tybalt, etc.
Out of the four options given in this question, Friar Laurence is the best example of a round character. He is the one who marries the two protagonists of the play, and prepares a potion that is a large part of their plan. Friar is involved in the main plot, and plays a crucial role in it. Abram is Montagues' servant, who fights with Sampson, the Capulets' servant. These are two minor, flat characters. Moreover, Lord Montague, Romeo's father, is a flat character, and is not involved in the main plot as much as Friar Laurence is.
