The correct answer is: To persevere when hardships press.
To stand to one’s guns means to continue to do something even when it is difficult or dangerous. It is often used in the context of a battle, where soldiers are told to stand to their guns even when they are under fire. However, it can also be used in a more general sense to refer to any situation where someone is facing adversity.
The other options are incorrect because they do not accurately reflect the meaning of the phrase “to stand to one’s guns.” Option A is incorrect because it suggests that the person is keeping their guns close to them for protection. However, the phrase “to stand to one’s guns” does not mean to hide or protect oneself. It means to continue to fight or persevere. Option B is incorrect because it suggests that the person is simply enduring hardship. However, the phrase “to stand to one’s guns” implies that the person is actively fighting against hardship. Option C is incorrect because it suggests that the person is maintaining a dignified and unbending attitude. However, the phrase “to stand to one’s guns” does not necessarily mean that the person is being dignified or unbending. It simply means that they are continuing to fight or persevere.
