I relieve the the correct answer would be A. B is not logical since that comes in act 4, it’s Ophelia and his love for her that troubles him. C seems ridiculous. D should be the death of his father at the hands of his uncle, Claudius.
Throughout most of the play, Hamlet is troubled by (a) his own tendency to hesitate and overthink.
In the play Hamlet by William Shakespeare, it is Hamlet's tendency to overthink what makes him fail. Instead of killing Claudius immediately after finding out he killed his father, Hamlet hesitates about murdering his uncle. This is presented in a clear way in Act 3 Scene 3 when he is about to get revenge by murdering Claudius but he ends up overthinking if it is the right thing to do since his uncle is praying in that moment. The "To be or not to be" soliloquy also shows Hamlet's tendency to overanalyzing situations, which, at the same time, is what ends up causing his failures.
