To simplify the expression \( 1008 \cdot 1007 \) using the Product Rule of Exponents, we can rewrite the bases with an exponent.
The expression leverages the property: \[ a^m \cdot a^n = a^{m + n} \]
Here, we have: \[ 1008 = 100^8 \quad \text{and} \quad 1007 = 100^7 \]
So, the expression becomes: \[ 100^8 \cdot 100^7 = 100^{8 + 7} = 100^{15} \]
Thus, the correctly simplified expression is: \[ 100^{15} \]
Therefore, the correct answer is: 10015.
