Answer:
The Chronicles of Narnia by C. S. Lewis is a fantasy fiction.
Treasure Island by Robert Louis Stevenson is an adventure fiction.
Pride and Prejudice by Jane Austen is a romantic fiction.
The Time Machine by H. G. Wells is a science fiction.
Explanation:
A fantasy fiction is a literary genre whose plot is set in a fictional universe. It is very much inspired by myths and folklore, and it usually involves fantastical elements such as witchcraft and magic. That definition matches the definition given for The Chronicles of Narnia - a series of books about four young siblings. Together, they travel to the magical world of Narnia and join a war that pits good against evil.
A, adventure fiction is a literary genre in which the characters find themselves in a situation of extreme danger. The plot is fast-paced and full of action. The characters usually have some type of task to complete in order to save themselves or even the whole word. That definition matches the one given for Treasure Island - the exciting story of a boy named Jim Hawkins. Jim finds the map to a treasure and goes on a journey to find it.
A romantic fiction is a literary genre whose plot revolves around a love story. The characters usually face some hardships and misunderstandings before they can finally be united in their love. That definition matches the one given for Pride and Prejudice - a love story between Mr. Darcy and Elizabeth Bennet set in eighteenth-century England.
Finally, a science fiction genre's plot revolves around technology and the possibilities related to it. They will most likely involve space traveling, time traveling, communication with other planets' species, and changes in the environment, among others. That definition matches the one given for The Time Machine - the story of a time traveler. He travels 800,000 years into the future and sees strange creatures.
