The equation displayed is $t(1) = t$, and you are being asked to identify the property related to this equation from the given options.

This equation suggests that multiplying or applying the operation to 1 leaves the function $t$ unchanged, which is characteristic of the identity property.

The identity property states that when you apply a specific operation (in this case, multiplication) to the number 1, it does not change the other number involved in the operation.

Thus, the correct choice is:

• identity

Would you like further clarification or more examples? Here are some related questions to explore:

1. What is the identity property in addition?
2. How does the identity property apply to matrices?
3. Can you explain how the identity property works in other number systems like integers or rational numbers?
4. What are some other properties like the identity property in algebraic structures?
5. How do identity elements behave in group theory?

Tip: Remember, the identity property for multiplication involves the number 1, while for addition, it's 0.
