Final answer:
The statement that Lady Macbeth suffers from a fatal illness is (B) false; her afflictions are psychological, stemming from guilt and acts of betrayal, rather than a diagnosed physical disease.
Step-by-step explanation:
The assertion that Lady Macbeth suffers from a fatal illness is false. Shakespeare's play 'Macbeth' describes Lady Macbeth's descent into madness, which is marked by guilt and hallucinations due to the heinous acts she partakes in, such as plotting to kill King Duncan.
However, there is no mention from any doctor that her condition is a fatal physical illness. Instead, she suffers from a tumultuous psychological state that leads to her sleepwalking and ultimate demise. The passages provided discuss various aspects and characters of Shakespearean tragedies but do not confirm a fatal illness for Lady Macbeth.
