In which type of purchasing scenario are suppliers most prone to feeling anxious and compelled to perform at their highest level?

Explanation

Suppliers tend to experience the most pressure during a modified rebuy because buyers are reconsidering previous purchases with some changes, prompting suppliers to make a strong impression. In contrast, new task buying involves entirely new purchases but suppliers may not yet feel the same pressure. Straight rebuys are routine with minimal pressure, and indirect rebuys typically involve less direct supplier involvement.
