The team was excited _____________________ the results of their hard work.

The correct answer is "about seeing" because it accurately reflects the way the feeling of excitement is typically expressed in English. The phrase "excited about" is commonly used to convey enthusiasm or eagerness regarding something that is anticipated or forthcoming, such as results in this case.

This construction emphasizes the subject's anticipation and positive emotional response to the outcomes of their efforts. Other options do not convey this same nuance. "With seeing" would imply a more immediate or hands-on involvement and is not the standard expression to denote excitement. "For seeing" suggests a purpose rather than an emotional response and does not fit the context of expressing excitement. "At seeing" could imply a reaction to something that has already happened, which doesn't align with the forward-looking nature of being excited about results that are to come. Thus, "about seeing" captures the intended sentiment most accurately.
