Final answer:
The character Filby does not describe Professor Dudley in 'The Time Machine', and Professor Dudley is not a character in the novel by H.G. Wells. The excerpts provided do not relate to this book or provide a description of Professor Dudley.
Step-by-step explanation:
In "The Time Machine," the character Filby does not describe Professor Dudley; in fact, Professor Dudley is not a character in the H.G. Wells novel. The provided excerpts do not relate to "The Time Machine" but seem to come from various other works of literature, none of which give a description of a character named Professor Dudley by someone named Filby. Therefore, the correct answer to this question cannot be provided based on the given excerpts. If the student is referring to a different text in which a character named Filby describes someone named Professor Dudley, they would need to provide the correct context for an accurate answer. As it stands, the options listed (a. Insane, b. Bitter, c. Mad, d. Intellectually challenged) are not applicable to characters within "The Time Machine."
