Answer 1

The most accurate answer to how the environment of Arabia served as a form of protection during much of the region's history would be:

Its extreme heat and arid conditions kept invaders from attacking settlements.

The harsh climate and desert landscape made it challenging for large invading forces to sustain themselves, thus providing a natural form of protection for the inhabitants of the region. Other options, while they may have some relevance, do not directly address how the environment served as protection in the same way.
