Final answer:
Mont Blanc is engaging in 1) product bundling by offering the pen, passport, and portfolio together, which is a strategy that often allows consumers to receive a better price than buying the products separately.
Step-by-step explanation:
Mont Blanc is engaging in product bundling when it advertises the Mont Blanc pen alongside a passport and an embossed leather portfolio. This marketing strategy involves selling two or more products or services together as a combined package. Product bundling typically offers advantages to consumers by providing a better price for the bundle than if the products were purchased separately. An example of this is when cable companies offer products like cable, internet, and a phone line at a special bundled price, which can be more economical than purchasing each service individually.
