The correct answer is B. Sacred.
Sacred means “holy” or “consecrated to a deity.” It is often used to describe places of worship, such as churches, mosques, and temples. It can also be used to describe objects that are considered holy, such as religious texts and artifacts.
Decayed means “in a state of disrepair or decomposition.” It is often used to describe buildings, structures, or objects that are old and falling apart. It can also be used to describe people or animals that are sick or dying.
Historical means “relating to or belonging to history.” It is often used to describe events, people, or places that are important or significant in history. It can also be used to describe things that are old or outdated.
Ancient means “of or relating to the distant past.” It is often used to describe things that are very old, such as civilizations, buildings, or objects. It can also be used to describe things that are no longer in existence.
In this case, the correct answer is B because “hallowed” means “holy” or “consecrated to a deity.” This is similar to the meaning of “sacred.” The other options are not as closely related to the meaning of “hallowed.”
