It is likely that Tom picks Myrtle because he thinks she will be an easy woman to control. She is not wealthy, powerful, or socially connected, so she doesn't pose much of a threat to him. Myrtle also readily accepts Tom's fabricated story about being unable to divorce Daisy because "she's a Catholic."
"Be not her maid, since she is envious." -> Don't serve her; she's jealous.
"That which we call a rose / By any other name would smell as sweet." -> Names are just labels; they don't mean anything.
"O! that I were a glove upon that hand, / That I might touch that cheek." -> I wish I could touch her face.
"Her eye discourses; I will answer it." -> She speaks with her eyes.
C, i think is the answer.
