portability
limited supply (scarcity)
durability

Explanation:

First Question:

• For the first option: Durability is about how long money lasts, not portability. Eliminate.
• Second option: Portability isn't about scarcity. Eliminate.
• Third option: Portability doesn't relate to government tracking difficulty. Eliminate.
• Fourth option: Digital currency (like debit card balances) can be carried as data, so you can have large amounts without physical weight, which is portability. Correct.

• Divisibility: About splitting money, not related to home printing. Eliminate.
• Portability: About carrying money, not affected by home printing. Eliminate.
• Limited Supply (Scarcity): If everyone can print currency, it won't be scarce anymore. This characteristic fails.
• Durability: About how long money lasts, not related to home printing. Eliminate.

Answer:

The correct option is: It allows you to carry large amounts of wealth without physical weight.
