How many acres were provided under Military Headrights to soldiers who came to Texas between March 2 and August 1, 1836?

The correct answer is that soldiers who came to Texas between March 2 and August 1, 1836, received 1 league under the Military Headrights system. This system was established to reward those who participated in the Texas Revolution, acknowledging their service and sacrifices. A league is specifically understood as a measure of land equivalent to approximately 4,428 acres; however, in the context of this question, the term "1 league" is the correct identification of the Military Headright for the soldiers within the specified timeframe.

The other options represent varying common land grants or surveys that apply in different contexts, but they do not accurately reflect the specific headright amount designated for soldiers during this period. The emphasis of this headright system was to encourage enlistment and support during the struggle for independence, and 1 league was established as the incentive for such contributions.
