Answer:
The evidence from Macbeth by William Shakespeare that supports the idea that Lady Macbeth believes her husband to be weak and coward is B: Wouldst thou have that / Which thou esteem'st the ornament of life, / And live a coward in thine own esteem.
Step-by-step explanation:
In these lines, and the one that follows in her speech, Lady Macbeth expresses her feelings about her husband being a "coward" and having a low self esteem when she says: "As thou art in desire? Wouldst thou have that / Which thou esteem'st the ornament of life, / And live a coward in thine own esteem,". In the following line her beliefs develop a little bit more when she adds: "Letting 'I dare not' wait upon 'I would'," I think it is very clear that she thinks he doesn't dare to be brave and would rather live with fear than act based on his beliefs, that is why I chose the second option.
