The correct answer is A. 5 kW.
An IVMIM uir consumer is a type of industrial, commercial, or institutional (ICI) customer that has a connected load of less than 5 kW. These customers are typically served by a single-phase distribution transformer.
The other options are incorrect because they are too high. A 40 kV transformer is typically used to serve a large industrial customer, while an 80 kW or 120 kW transformer is typically used to serve a large commercial or institutional customer.
I hope this helps! Let me know if you have any other questions.
