To determine the correct word to fill in the blank, let's analyze the given options in context.

1. Invaluable: This means something that is extremely valuable or priceless. This might not fit since we are generally discussing options rather than their intrinsic value.
2. Viable: This means capable of working successfully or feasible. It fits the context of discussing options that can be realistically pursued or implemented.
3. Enviable: This means something that is desirable and likely to attract envy. While it could fit in some contexts, it's less about practicality and more about desirability.
4. Liveable: This typically refers to conditions or places that are comfortable for living. It doesn't fit well in the context of discussing options.

Final Answer

The best fit for the blank is viable. So, the completed sentence would read: "As a result, these could be seen as being the two most viable options."
