Heirs

The most appropriate option to fill in the blank is heirs.

The word heir means a person who inherits something, especially property. In this context, the sentence is saying that we are heirs to the true legacy of humanism, and we must never forget this. This means that we are the inheritors of the values and principles of humanism, and we must always strive to uphold them.

The other options are not correct.

• Hair is the plural of hair, which is a strand of something that grows on the head or body of a person or animal. It does not make sense in this context because we are not inheriting hair.
• Hares are a type of mammal that is similar to a rabbit. It does not make sense in this context because we are not inheriting hares.
• Here means in this place. It does not make sense in this context because we are not inheriting a place.
