What can be inferred about the invaders despite their limitations?

The choice that indicates the invaders' success in the battle, despite their limitations, is correct because it suggests that they were able to overcome obstacles and possibly achieve their objectives. This implies an ability to adapt or utilize their resources effectively, thereby leading to a victory. Winning the battle often requires not only strength or preparation but also the ability to navigate limitations strategically.

The other options would not accurately reflect the situation of succeeding despite limitations. Indicating that they lost the battle or were well-prepared contradicts the implication of having succeeded. The statement about having a strategy does not directly correlate with the outcome of victory versus defeat, making it less definitive in conveying that they triumphed.
