Among the transformer ratings present in the scenarios, which is the largest?

Explanation:
Understand that a transformer’s rating in kilovolt-amperes (kVA) shows its capacity to deliver apparent power. The rating is a capacity figure and, unlike kW, it isn’t tied to power factor, so you compare the numbers directly. In the set given, the highest value is 225 kVA, which is larger than the others (150 kVA, 75 kVA, and 45 kVA). That means it can carry a higher load before reaching its limit. For practical selection, you’d choose a transformer with a rating at least equal to the required load in kVA, keeping in mind that the actual usable power in kW depends on the load’s power factor.
