Scan the following book titles which one would you expect to focus on the adventures of a guide dog for blindness

Your question is incomplete, but according to my research, the correct answer is MOVING THROUGH THE DARKNESS.
Dogs are sometimes used as guide for blind people to take them from one place to another. A book which wants to focus on the adventure of a guide dog for a blind person will describe how the dog is able to guide its master through the darkness of his blindness. Moving through the darkness will be a suitable title for such a book.

The answer would be a.
