I think that Shakespeare is referring to Winter. I think so because he says, “Yellow leaves, or none, or few do hang. Upon those boughs which shake against the cold.” Which means that the leaves are falling off of the trees and also that the tree stumps are shaking against the cold. All these things happen is winter. Hope this helped!
An abstract noun is something that isn't tangible or anything you can touch. Mainly it is talking about emotions. Based on that I would say it would be B. It says hoped which is an emotion
