Individuals who are impetuous tend to act:

The term "impetuous" describes someone who acts quickly and without careful consideration. Individuals who are impetuous tend to act on impulse, driven by strong emotions or a sudden urge, rather than through rational thought or careful planning. This characteristic leads to actions that might be seen as reckless or hasty.

Option C captures this essence of acting "with undue haste and lack of consideration," emphasizing both the speed of the action and the disregard for potential consequences. In contrast, the other options imply a level of thoughtfulness or deliberation, which does not align with the definition of impetuous behavior.
